Oh dear, summer must really be over. Kids are back in school, birds are flocking before heading south for the winter, Labor Day is just around the corner, and Zac Efron and Michelle Rodriguez‘ summer fling is over.

~sigh~

According to Us Weekly, the That Awkward Moment actor and Rodriquez are no longer dating, or getting it on, or whatever it was they were doing in Italy and Spain over summer.

Sources told the magazine the duo ended their fling after having a knock-down-blowout fight in Ibiza, Spain over the Fast and Furious‘s BFF and former girlfriend Cara Delevingne.

“Cara was always being mentioned,” another source told Us Weekly, referring to the Vogue cover girl. “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.'”

That’s too bad because the eye-candy factor of their hook-up was pretty spectacular.

“Michelle is going to do her own thing. Zac knew this about her when he got with her,” one source said, adding that he is still sorta pining for her.

“He’s very into her though, and perhaps more than she’s into him,” said the source.

The unlikely couple were endlessly photographed frolicking on a boat off the coast of Italy in early July, getting hot and heavy on the dance floor at an Ibiza nightclub, galloping around on horseback (Efron shirtless, thank you very much), and dining out with other holiday-goers just a few weeks ago.

Efron, who is currently filming We Are Your Friends after his extended holiday, took the ALS Ice Bucket Challenge to benefit amyotrophic lateral sclerosis, or Lou Gehrig’s Disease, on Tuesday with Ashley Tisdale.

He then nominated Robert Pattinson and, yeah, his video is pretty hilarious.

#RobPattinson's not on social media, so he asked me to post his @ALSAssociation #IceBucketChallenge! It's hilarious! http://t.co/GIBRoGsReY
