She entered the final year of her teens on Thursday, when she celebrated her 19th birthday with friends and family.
And Kaia Gerber took a part of her celebration to Instagram, where she shared a plethora of snaps with pals, including one of her kissing a blonde beauty.
The catwalk star, daughter of supermodel Cindy Crawford and business mogul Rande Gerber, added a heart emoji to the shot of herself holding close friend Heather Sage Blair in a tight clinch.

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.

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’.
