Shanna Moakler and Oscar De La Hoya reunite for daughter's high school graduation

She did it!

Atiana De La Hoya, who is Oscar De La Hoya and Shanna Moakler's 18-year-old daughter, graduated high school on Thursday, and her mother posted a sweet snapshot of the momentous occasion.

In the photograph, Atiana is wearing a sexy LBD underneath her gold graduation gown with a traditional Hawaiian lei around her neck. Ataiana's parents are on either side of her, with the legendary boxer rocking a short-sleeved button down and the former beauty pageant queen keeping it casual with jeans and a black tank.

While it's no surprise Oscar and Shanna reunited for their daughter's graduation, the sighting of the two exes together is quite a rarity. They got engaged prior to the 1999 birth of Atiana, but their relationship came to an end in 2000 when Shanna, who was at home watching the Latin Grammy Awards, saw her then-fiance bring another woman to the show.

With the dramatic ending to their relationship, it's no surprise that their relationship post-breakup has been quite rocky. However, it's nice to see these two exes set aside their differences for their daughter!

Following her breakup with Oscar, Shanna went on to marry Travis Barker, the drummer for Blink-182. Their life as a married couple was famously documented on the hit MTV reality show, "Meet the Barkers." They divorced in 2008 after four years of marriage.

Oscar, on the other hand, got married shortly after his split with Shanna to the same woman he escorted to the Latin Grammy Awards, Puerto Rican singer Millie Corretjer. They have two children together, Oscar Gabriel and Nina Lauren.

Atiana has yet to reveal her post-high school plans, but she definitely has a future in modeling. The brunette beauty has 63,000 Instagram followers (and counting!) and she's definitely giving us serious Kylie Jenner vibes with her aesthetic.
