We wonder if the British beauty knows her ex-girlfriend is still hung up on her?

Cara Delevingne went for a stroll around New York City with pal Zoe Kravitz today, and the model looked stunning in a simple t-shirt and gold sunglasses. We can see why former lady love Michelle Rodriguez is unable to get over her!

According to reports, the Fast And The Furious star's brief relationship with Zac Efron fizzled because she couldn't stop talking about the Vogue cover girl. "Cara was always being mentioned. Cara would spend time on the same boat and Cara and Michelle have all the same friends. It was just a lot. It was always, 'Cara, Cara, Cara'," a source told E! News.

The High School Musical actor sounds like he was the one that was more into it to begin with, too. "It had just been a casual hookup for Zac and Michelle. They were having fun. She is such a great person and he naturally gravitated towards that. They saw comfort in each other and connected on their experiences in rehab and were really good for each other. They were there for each other," the source adds.

Three's a crowd!
