Oops!

Looks like Chloe Grace Moretz's pretty velvet blouse couldn't withstand a busy night of press on Monday, literally coming apart at the seams. The 19-year-old Neighbors 2: Sorority Rising actress wore the delicate purple top during her appearance on Bravo's Watch What Happens Live!, which actually ripped in the back as she was signing autographs for fans.

Still, Moretz looked flawless in the hard-to-pull-off blouse from the front, pairing the turtleneck with chic black trousers and strappy stilettos.

Moretz's Watch What Happens Live! appearance was definitely notable, as she finally confirmed her relationship with Victoria and David Beckham's 17-year-old son, Brooklyn Beckham.

"I think the more I don't make it mysterious, the more people don't care, so yes, we're in a relationship," she shared.

"He's a great dad, she's a great mother," she added about her beau's famous parents. "They genuinely are very good parents [and] that's what matters most. ... They made a pretty son."

"Sorry mom," he joked.
