She appeared to be fine with her ex-girlfriend moving on after their split, but a new report suggests that model Cara Delevingne is actually a bit upset over the fact that Michelle Rodriguez is now dating men again.

Cara Delevingne Hooking Up With Zoe Kravitz?

According to Yahoo! News July 20, the 21-year-old face of several fashion campaigns is actually struggling with the fact that her openly bisexual ex-girlfriend moved on so quickly with a member of the opposite sex, after the two had a brief but intense affair earlier this year.

"Michelle was the only person Cara felt comfortable about having a serious relationship with since she hit the limelight," a source said. "She's over her, but it's never easy seeing your ex move on, especially when it's with somebody of the opposite sex. She misses having someone special in her life."

Zac Efron Adores How 'Free-Spirited' Michelle Rodriguez Is?

Rodriguez sparked rumors she was dating heartthrob Zac Efron earlier in July, after photos surfaced of the two making out while vacationing in Italy together.

Considering earlier comments Delevingne has made about the opposite sex, she very well could be unhappy with her former love's decision to move on with the young actor.

The model, who has never placed a label on her sexual orientation, has admitted that she generally prefers the company of women these days, telling The Telegraph in June that she finds men tend to have ulterior motives when it comes to relationships with her.

 "I don't meet men now who just want to be my friend. It just doesn't really happen that much," she said at the time. "They're just shallow like that. Unless it's one of my girlfriend's boyfriends, most guys are not like, 'Oh, we should just be mates.' I think it's harder to become friends with guys, because guys just want to have sex with you."
