Their family reality TV show Keeping Up With The Kardashians shows every little detail of their personal lives.
And while Bruce Jenner is happy to let the E! cameras film the ups and downs of family life, he got a little camera shy in Malibu on Sunday.
Bruce enjoyed some father/daughter bonding with his youngest child Kylie, 16, but chose to hide his face under a motorcycle helmet the entire time.
Suddenly shy? Bruce Jenner enjoyed some bonding time with Kylie, 16, in Malibu on Sunday but hid his face under a motorcycle helmet
The former Olympian was completely unrecognisable under the helmet and would have likely passed undetected if his famous daughter had not been by his side.
Well hidden was Bruce's newly bouffant hairdo, which he has been sporting since his split from Kylie's mother Kris last year after over 20 years of marriage.
Bruce, 64, wore a blue T-shirt, jeans and trainers and was, as ever, wearing his wedding ring.
Hiding his long locks? Bruce's long Ombre hair was hidden under his helmet and he must have been sweating in the LA sunshine
Kylie was much more appropriately dressed for the sunshine in a long skirt and a cropped grey top.
She added biker boots and protected her eyes from the sunshine with a pair of oversized shades.
Perhaps she could suggest sunglasses to her dad rather than the huge helmet he did not want to remove.
Easy rider: Bruce zoomed up on his motorcycle to meet Kylie for some bonding in Malibu on Sunday
While Bruce arrived for the meeting on his motorbike, Kylie - who received a $125,000 Mercedez-Benz SUV for her 16th birthday - arrived in her own car.
While she was delighted to get her permit in August, followed by her car, 18 days later Kylie managed to crash it.
The teenage reality star got into a three car chain reaction collision in Los Angeles.
Kylie was driving her new wheels around Calabasas when she slammed into the back of a Toyota which then subsequently hit a Volkswagen SUV.

After the smash, which occurred around 5pm in the afternoon, Kylie immediately jumped out her vehicle and made sure everybody was OK whilst apologising profusely.
No passengers were injured in the accident.
According to TMZ, Kylie exchanged insurance details and other information with the other drivers and then left.
Police arrived to the crash site not long after, but Kylie was long gone.

Kylie turned sweet sixteen on August 10 and just two days later obtained her license so she could start driving her gas-guzzler all on her own.
No doubt Kylie was keen to spend some quality time with her dad, as he moved out of the family home in Calabasas after he split from Kris last year.
Daddy/daughter time: Former Olympian Bruce Jenner hung out with his youngest daughter Kylie in Malibu on Sunday
Even though Bruce still wears his ring, Kris has insisted they won’t reconcile because their marriage had turned unhealthy by the end.
During a podcast interview with Kathie Lee Gifford, Kris, 57, explained: ‘We are better people and happier just spending time apart than we are spending time together. We decided this was best for our family. We came to a place where this isn’t healthy, the way we were treating each other.’

However, she insisted they will always love each other and have no plans for divorce.
'I was so blessed to meet Bruce Jenner,' she said. 'I adore Bruce. Bruce and I are and will remain best friends. We’re just separated, we’re not divorcing.
'And what happens in life is that we are better people and happier spending time apart than together. This is the best for our situation and we’re keeping it real tight and private. It’s just what we need to do right now.
