Leonardo DiCaprio and Blake Lively have ended their summer fling. The Gossip Girl star's rep has confirmed the split to X17online with the following statement, "They have split."

The twosome went public back in May while sailing aboard Steven Spielberg's yacht in Monte Carlo.

Since then, Blake, 24, and Leo, 36, have been seeing hanging out at Disneyworld and shopping together in Beverly Hills. Oh, well ... at least they had fun over the past five months!

Reps for both stars add the couple "remain friends."

Before the two hooked up, Leo had been dating model Bar Rafaeli on-and-off for five years, while Blake spent three years dating Gossip Girl co-star Penn Badgley.
