Heather Locklear is one proud mama.

On Saturday, the “Melrose Place” alum, 58, celebrated daughter Ava Sambora‘s college graduation from Loyola Marymount University, a private university in Los Angeles, with at-home festivities amid the coronavirus pandemic.

“Congratulations baby girl! We are so proud,” Locklear shared on Instagram, posting a photo of Ava’s college portrait.

Locklear — who shares 22-year-old Ava with ex Richie Sambora — also posted a photo of a tiered cake and a cutout of the recent grad.

On Friday, Ava posed for an outdoor shot, modeling her graduation cap with a purple sweatshirt and black boots.

“Tomorrow is the big LMU graduation at home for my baby,” Locklear wrote Friday.

Ahead of Ava’s graduation, Locklear announced last month she is one-year sober.
