Since her divorce in 2010, her son Louis has been the only man in her life.
But things seem to be changing for Sandra Bullock, who is rumoured to be 'flirting' with Captain America star Chris Evans.
And although 17 years older than her rumoured beau, the 49-year-old looked more than a match for any competing young starlets as she flashed her toned legs during the school run in Los Angeles on Thursday.
Sandra showed off her enviable physique in a frilly brown and white peasant dress, which she teamed with studded sandals and a pair of over-sized dark glasses.
Pulling her hair back from her face with a thick black band, the Oscar winner revealed the kind of flawless skin that would make a 20-year-old envious.
After divorcing cheating husband Jesse James in 2010, Sandra has been more focused on her home life that dating.
However, that may be set to change if romance continues to blossom with Chris Evans, 32.
Sandra, who will be turning 50 in July, is said to have been 'flirting' and seeing more of her friend - who previously confessed to a boyhood crush on the brunette beauty - and now pals are desperate for them to officially embark on a relationship.
A source told America's OK! magazine: 'They have been talking more than ever and they flirt anytime they spend time together. She's been his dream girl for most of his life, so it would be a fairy-tale ending for Chris.
'Friends are pressing Sandra to just finally give in and take their relationship to the next level. It's just a matter of time.'
The pair were spotted enjoying supper at Hollywood hot spot Cecconi's in May, along with comedienne Chelsea Handler.
'Chelsea kept chiming in and they would include her but there seemed to be a connection between Chris and Sandy.'
However, the Blind Side actress has plenty to keep her busy whether or not the romance develops.
Following the success of Gravity, Sandra is currently filming The Minions, in which she lends her voice to animated super villain Scarlet Overkill.
It has also been announced she is set to reprise her role in Heat 2 alongside Melissa McCarthy, after the first installment proved to be the the most successful comedy of 2013 at the domestic box office.
