Lily Collins  Good Morning America heels dress gma Black Sheep Syndication

Young love doesn't last forever! British actors Lily Collins and Jamie Campbell Bower have broken up, reports Us Weekly. But you wouldn't know that from these photos! Just a day before announcing the split, Lily looked stunning for an appearance on Good Morning America in New York City on Wednesday. The couple has been dating since July 2012 and met while shooting the fantasy flick, The Mortal Instruments: City of Bones, which hits theaters Aug. 21. A source tells Us Weekly, "They remain very good friends."

Nothing makes a girl look her best like a break up! Lily seems to be taking the rift in stride, strutting her stuff in a Valentino frock and Jimmy Choo heels through the city streets.

However, things could be getting a little awkward for the former couple in the coming weeks -- the twosome are currently promoting their new film and are on a nationwide press tour together, which includes appearances, interviews and more. Despite being in close quarters, the source also added, "They've been really good about doing the press tour together for their movie. They were able to stay friendly." Let's just hope that neither one of them brings around a new paramour until the press tour is over!

As the old saying goes, there are plenty of fish and the sea and it seems as if neither Lily or Jamie have had any problems in their past catching anything. Lily previously dated her Abduction costar Taylor Lautner from November 2010 to September 2011, and also had a romance slam dunk with Zac Efron for three months in 2012. Campbell Bower is no slouch himself; the Twilight Saga: Breaking Dawn star was previously engaged to his Harry Potter and the Deathly Hallows: Part 1 costar Bonnie Wright.

If Lily keeps looking like this -- she is sure to have a new man in no time!
