Zac Efron & Michelle Rodriguez
This was a summer fling no one saw coming. Zac Efron was spotted packing on the PDA in Sardinia, Italy with Fast & Furious actress Michelle Rodriguez, nearly 10 years his senior. The two were seen flying into Sardinia Airport in a private jet on July 4th, 2014, and were later caught cuddling and kissing on a boat together. Not too long after pics of their romance surfaced, the relationship reportedly fizzled.
