They reportedly had an amicable split last year, but according to new reports, Cara Delevingne is still having a hard time being in the same room as her ex, Fast and the Furious star Michelle Rodriguez.

According to The Mirror, the former flames had an awkward run-in while both attending the Grisogono Bash at the Cannes Film Festival earlier this week, when Delevingne, 22, arrived at the bash with her new girlfriend, St. Vincent, 32--and freaked when she found out Rodriguez, 36, was also at the glitzy party.  

"I can't face seeing her," sources told the paper the model/actress said after learning of Rodriguez's attendance at the event, making an uncharacteristically early exit from the bash with her new girlfriend.

"Cara and Michelle haven't spoken since the split and they aren't friends anymore," the source added. "Cara was with her new girlfriend and she couldn't face any kind of awkward confrontation. As soon as they heard Michelle had arrived they left. Cara was telling her pals she just didn't want the hassle.She left the bash at about 1 am and headed back to her hotel. Very tame behavior." 

Rodriguez and Delevingne dated from early 2014 until about midway through the year, breaking up about one year ago. Since then, both went on to other relationships. Rodriguez enjoyed a brief fling with actor Zac Efron over the summer, while Delevingne dated her Tulip Fever co-star Jack O'Connell before hooking up with St. Vincent this past December.
