Rumors continue to fly about the reasons behind model Cara Delevingne and actress Michelle Rodriguez splitting up, and the newest batch claim that Delevingne couldn't handle the pressure of both a hectic work schedule and a relationship.

A source reportedly told Look magazine that the stress was too much, and Delevingne decided it was time to cool things off as a result.

"They were still talking but things went from serious to casual about six weeks ago," the source said. "Cara realized there were too many sacrifices to make things work, and she couldn't deal with the drama of juggling work with her relationship."

"Then, Michelle started going all gooey-eyed over Evan [Rachel Wood], which was reported back to Cara and she took a dim view of it," the source added. "There was no going back. She knows Michelle can become slightly obsessed with other women, and she was not prepared to waste her time."

Rumors previously flew that Rodriguez had hooked up with the other, also newly single actress, but Wood vehemently denied the two had ever gotten together.

However, if rumors are true that Delevingne couldn't handle juggling a full-fledged relationship, it may explain several photos that have popped up recently of her kissing other people-both men and women-meaning she may just be casually dating around instead.

TMZ first reported on a lip lock in New York that captured Delevingne and Victoria's Secret model Karlie Kloss kissing in the street, sparking rumors that the two models were now an item.

It wouldn't be the first time Delevingne has locked lips with another female-singer Rita Ora posted a photo on Instagram June 5, and the model also locked lips with actress Sienna Miller last year.

Delevingne could also be casually dating a male as well-fashion journalist Yale Breslin. A photo appeared on both their Instagram accounts June 11, showing them kissing with their eyes closed.

Though she has been mostly linked to other women lately, Delevingne did reportedly date One Direction's Harry Styles.
