The singer spent most of the day watching the World Cup game and it clearly got her all fired up for the night
The naughty singer celebrated July 4th along with most of the rest of the showbiz world, and stuck with her no bra theme for the night.
Showing off her frilly red knickers (and we're almost positive no other underwear at all), Ri covered her slim body in a flimsy piece of red material she obviously wanted to pass off as a dress.
The tiny dress fell to just below her bum, and the star flaunted her perfect pins as she arrived at Hooray Henry's in West Hollywood.
It must have got a bit chilly later on, because she covered up in a big grey jacket - but not before we'd all got a flash of everything.
She must have been fired up from all that football commentary hours before.
Rihanna got really into the Brazil v Colombia game, and posed topless covered in a load of flags to cheer the winning team on.
She also took the opportunity to make a young girl's day/entire life when she posted a vine of her in the audience captioned: "Colombian beauty."
Best. Surprise. Ever.
The close-up shot shows the brunette beauty showing off a wide grin with heavy red lippy and a red top on - and we agree with Ri, she's a stunner.
It's unclear exactly who the mystery woman is but she's no doubt feeling pretty chuffed.
Rihanna poses topless with baby: Singer criticised for posting semi-naked photographs with young niece
But this time it’s who she’s decided to pose with that has raised eyebrows.
The singer tweeted three photographs of herself holding her baby niece.
In the first two, she can be seen cradling the child in tracksuit trousers and a crop top as she kisses the baby lovingly on the forehead.
In the third image, however, she’s completely topless, seemingly wearing nothing but a lacy pair of French knickers and she clutches the baby – dressed only in a nappy – to her chest.
“Aunty and Me #girltime #twinzies,” she posted alongside the image on Twitter.
But the shot didn’t have the effect she perhaps desired (or maybe it did – and that’s exactly the point of it).
While scores of “Awww” and “Adorable!” and “<3s” were flung in RiRi’s @-tagged direction, Twitter feeds began to question why she thought posing semi-naked with an infant was a good idea:
After experiencing a backlash for her unapologetic brazen behaviour, she asked one reporter: “Do my tits bother you?”
A perfume advert to promote her new fragrance Rogue was also recently given "placement restriction" after it was deemed too "sexually suggestive" to be viewed by children by the Advertising Standards Agency.
The campaign, shot by photographer Mario Sorrenti, featured a topless Rihanna leaning with her legs raised up against a perfume bottle.
Rihanna Tweets Hot Topless Picture To Celebrate Brazil Win

Brazil edged through to the semi-finals of the World Cup yesterday, with pop star Rihanna being one of the people to send their congratulations to Luiz Felipe Scolari’s team. She had her own unique way of doing it, however – topless and covered in the nation’s flag. A keen follower of the World Cup on Twitter, it isn’t the first time that Rihanna has shown her body to celebrate a team this tournament.
Karrueche Tran proves she is no poor man's Rihanna with some sizzling snaps
Model Karrueche shows off her fabulous figure in some sexy pictures and proves she's every bit as hot as Ri-Ri
The 25-year-old model has shared a bikini picture on Instagram in which she bares more than a passing resemblance to her boyfriend's famous ex.
Wearing tiny denim shorts and an orange bikini top she flaunts a stars and stripes flag to celebrate Independence Day as she strolls on the beach.
The star also looked sensational while celebrating the launch of the new, Karrueche Tran limited-edition V/Sual tee in Glendale, California.
Karrueche was all smiles for the in store appearance at PacSun and she made sure she looked as hot as possible for the ocassion.
As she flashed her bra, showed off her taut midriff and rocked a pair of ripped skinny jeans, the star proved she's no poor man's Ri-Ri. (lol)
Exotic looking Karrueche, who is of both Vietnamese and African descent, dated controversial star Chris Brown, 25, for two years after he split up with Rihanna in 2010 following their volatile relationship.
Then after splitting up while Brown briefly re-kindled his romance with Rihanna, 26, they later reunited in May 2013.
The model insists the couple are in a "good place" in their relationship and Brown himself is well known for tweeting love notes about her in the social media.
Rihanna and Drake Break-Up News: Chris Brown In Again?
"To be honest, I don't want a serious relationship right now. I just want to have fun! I have three girlfriends and about 20 male friends. I just love listening to men - I always learn something." Rihanna told Bravo magazine. (note op: bravo magazine is pretty known to spread BS)
This concludes that Rihanna is temporarily off of the market, but reports involving Drake say that since breaking his heart, Drake's friends have been very protective.
Rumor has it that Nicki Minaj stands in the defense of Drake in his time of need. A source told Ok! Magazine recently that Rihanna "really broke his heart. Nicki wants to call Rihanna out on it. She's very protective of Drake."
While the rumors about the relationship kept piling on, Rihanna has been ignoring them in light of the 2014 World Cup matches she's been enjoying. She's been tweeting constanty on the matter posting things like, "Great job #USA I'm proud of you boys! You put your heart in it!!! What a match," which she wrote after the USA lost to Belgium on Tuesday.
The former lovers seem to be silent about their break-up. There are still no official statements from either of the two regarding the relationship, however, in other news Rihanna has been recently linked to Chris Brown again, despite previous altercations.
Rumors have been encouraging the two to hit it off again since Rihanna has already broken it off with Drake, but there's no response from either party floating around the Internet.
