It appears that Fast and the Furious actress Michelle Rodriguez and model Cara Delevingne have officially called it quits.

Michelle Rodriguez Jealous of Cara Delevingne's Friendship With Suki Waterhouse?

According to Sugar Scape, the couple, who was seen frolicking in the sea during a Mexican vacation together just last month, has officially cooled things off after rarely seeing each other in recent weeks following Delevingne's busy schedule keeping her abroad, while Rodriguez remained stateside.

However, according to TMZ, Delevingne was spotted leaving Loulou's Club in Mayfair, London April 29 hand-in-hand with 32-year-old actress Sienna Miller. The two had spent the night partying with Delevingne's fellow models, Naomi Campbell and Suki Waterhouse, but left together.

Cara Delevingne's Family Doesn't Approve of Relationship With Michelle Rodriguez?

Though there's no confirmation that the 21-year-old model is anything more than friends with the actress, Miller has had a history of infidelities. She and Jude Law reportedly had affairs on one another in the mid- 2000s, and she also had a widely-publicized affair with married actor Balthazar Getty back in 2008.

Though Delevingne and Miller are likely just good friends, the model could be seeking comfort with other partners simply because she is young and not ready to settle down, according to Celebrity Dirty Laundry. Rodriguez is 35, and the website claims the age gap could have taken its toll on the relationship.

 "Cara's definitely somewhat of a loose cannon, and she's notorious for partying and hooking up with people. How long can someone so young and care-free stay in a committed relationship?" the website wrote April 24. "Eventually, she won't want to be tied down anymore, and when that time comes, we can only hope that Michelle doesn't get her heart broken."
