Summer is almost over, but it looks like budding celebrity couples of 2014 have just started popping up. Will these summer flings last?

Last year, quite a number of summer couplings resulted in long-term relationships, engagements, and even babies!

This year, the world was shocked by the most unlikely pairs making their romantic involvement known.

Zac Efron and Michelle Rodriguez had been photographed being extremely touchy with each other during a vacation last month. The 'Neighbors' star was already comfortable enough to stay overnight at the 'Fast And The Furious' actress' home. They were spotted together again, this time, in Ibiza.

'True Blood's' Joe Manganiello coupled up with 'Modern Family's' bombshell Sofia Vergara. They apparently are the summer's sexiest celebrity couple for 2014.

'The Vampire Diaries' Ian Somerhalder has been doting on new girlfriend Nikki Reed, packing on the PDA while shopping at Trader Joe's. She also happens to be friends with his ex-girlfriend Nina Dobrev.
