Lily Collins Shuns Heartbreak At 'The Mortal Instruments: City Of Bones' Photocall (PHOTOS)

Lily Collins, daughter of Phil Collins, proves once again that average-looking people can have really beautiful children. And the Chanel-approved 24-year-old appears to be stepping up her style game all over Hollywood.

Now, we know it's hard to make promotional appearances with someone you just broke up with. Just ask "The Vampire Diaries" stars Nina Dobrev and Ian Somerhalder (although they may be secretly back together).

But Lily is doing a stand-up job promoting her new film "The Mortal Instruments: City Of Bones" with ex-boyfriendJamie Campbell Bower. First, the "Mirror Mirror" star stepped out last week looking stunning in Stella McCartney. Then, at the Hollywood premiere, the bushy-browed vixen wore a sexy white cutout dress. Finally, Collins arrived at a photocall for the movie in Mexico City on Monday wearing a decidedly younger ensemble consisting of a metallic striped t-shirt and pleated black skirt by Rachel Zoe, paired with black Brian Atwood pumps.

It also appears that Lily discovered bronzer, as her normally pale skin had an unusually healthy, peachy glow.

Will we ever see Lily sport a crop top again?

She could be the next Kristen Stewart:
