Rande, meanwhile, shared a snap of his only daughter from when she was 14. The photogenic beauty smiled brightly at the camera, makeup free, in a black bikini top.
‘Happy Birthday my little angel. I thought I was in trouble when I took this 5 years ago but your beauty on the inside has proven to be even bigger than your smile. I love you forever,’ he wrote in the caption.
Along with Kaia, Rande and Cindy are also parents to older son Presley, 21.

While the pair definitely seemed close, there didn’t appear to be anything romantic between the two but something may be on the horizon.
Jacob has kept quite quiet about his love life, but seems to meet his ladies on set.
He previously dated Kissing Booth co-star Joey King but had most recently been linked to his Euphoria co-star Zendaya, 24.
The Aussie actor and former Disney Channel star sparked romance rumors earlier this year after being spotted in NYC and Jacob’s native Australia together, but have since been quarantining on separate continents.

A source told E! News in an article Wednesday that Kaia and Jacob have been friends for some time.
‘Jacob definitely has interest in dating Kaia, but there is nothing serious going on there,’ the insider said.
‘They have many mutual friends and have hung out many times in the past. They both have very chill personalities and similar interests. Jacob makes Kaia laugh and her family adores him’.
Kaia has been keeping it friendly but they do flirt with each other, the source said, while adding, ‘She has told friends she is single and is only having fun and hanging out with people’.
