Chris Brown and girlfriend Karrueche Tran arrived at the ESPY's pre-party at Lure in Hollywood last night in his freshly-painted Lamborghini (apparently he paid $10,000 to get his whip painted the same color as our website logo), and after checking in with security, Chris and his lady love were denied entry so they hopped back in his ride and drove home!

Our photog on the scene tells X17online exclusively, "Chris didn't seem that upset about getting turned away -- rather than making a scene he and Karrueche quietly left."

So why did the duo get rejected from the venue? "My guess is because the club didn't want to deal with the risk of Chris getting into a fight with someone," our lensman added. "It's happened before, and it can get pretty ugly." Can't say we blame them!

Though he's reportedly been on the rocks with Karrueche over the last few weeks, apparently after seeing a recent interview of hers, he realized that he wanted to make some changes. Karrueche appeared on BET’s Just Keke the other day, and she spilled all sorts of secrets about their relationship, and she even broke down into tears!

“I’ve never dated a celebrity before so it was a very new to me," Karrueche revealed. "Paparazzi and all that. And then, even the situation with Rihanna, you know the reason why people tuned into this so much was because it’s relateable. I have girlfriends, I have family who’s gone through the same situation."

Karrueche continued, “It’s the case of the ex. We all go through it, do you know what I’m saying? But, however … in this case my boyfriend is a celebrity who’s ex-girlfriend is an even bigger (celebrity.) So not only am I fighting a battle with her, I’m fighting a battle with 14 million fans or however else. So, imagine how that feels for me when I gotta get on Twitter and see a bunch of stuff.” Hey, at least she's acknowledging that RiRi is more famous than Chris!

Karrueche then got teary when asked about the hardest thing about their love. “Um, jeez, I guess I would say the heartbreak because it was a real situation,” she said. Click thru to watch the clip!
