Blake Lively and Leonardo DiCaprio: It's Over!

After five months, Blake Lively and Leonardo DiCaprio have broken up. Reps for both confirmed the parting of ways, adding that they "remain friends."

First spotted together in Monte Carlo at the Cannes Film Festival, the couple embarked on a whirlwind, super-luxe summer love-fest spanning the globe.

During their time together, the Gossip Girl actress, 24, and Inception star, 36, were surprisingly open about their romance and seen frequently in public.

The pair's recent split is sure to come as a surprise to some DiCaprio pals, one of whom told Us Weekly that they'd "never seen him like this with a girl."

They spent much of the summer at DiCaprio's L.A. home, where Lively "spent the whole time baking. Leo's never dated a girl who can cook. He's smitten!"

After going strong all summer, the duo bonded with one another's parents. Echoed another insider later this fall: "I bet they get engaged in six months."

Apparently it wasn't meant to be, though. While sad for both, we wish Leo and Blake the best ... and have little doubt they'll find someone new if they want.

Instantly.
