The summer heat is on and it is bound to get even hotter with the latest Hollywood couples. From Miley Cyrus and Liam Hemsworth's' sudden engagement to Taylor Swift's newest boyfriend, here are all the hottest summer couples to keep all eyes glued on.

Miley Cyrus and Liam Hemsworth shocked fans, family and friends with the news of their engagement last May 31. While some have dubbed it as "likely to lead to divorce", Miley fans are saying it is a love that is sure to last a lifetime. The wedding is set this summer which is enough to make everyone wonder what the "Can't be tamed" singer will be wearing.

Another couple that is making summer waves is "The Amazing Spiderman's'" Emma Stone and Andrew Garfield. The two have been hitting up a lot of red carpet premieres together looking dashingly hot. Just in time for the blockbuster film to hit screens this July, Emma and Andrew are making their presence felt all over the world. Recently, both showed up in matching black outfits at the UK premiere of "The Amazing Spiderman".

Despite hoards of haters calling their relationship all for show, Kanye West & Kim Kardashian are turning a deaf ear to the world. "Kimye", as they have been dubbed, have been spotted indulging in over-the-top PDA. From buying expensive birthday presents to wearing matching suits, these two give meaning to a summer romance. Hopefully, their relationship will last longer than Kim's 72-day marriage with Kris Humphries.

One Direction cutie, Niall Horan, is also said to be Skype-serenading Demi Lovato. The two have not said anything final about their "rumored" romance. However, separate interviews of the two admitting their crush for one another is enough to keep fans on their toes.

The Coachella Arts and Music Festival was surely a hell lot of fun for Katy Perry. The "Fireworks" was spotted smooching and cuddling with "Florence and the Machine's'" Robert Ackroyd. It's an on-off and on again relationship for the two.

Singing sensation, Jordin Sparks has found her match in Jason Derulo. Apart from announcing their relationship earlier this year, Jason also suffered a major accident involving his spine. Thankfully, Derulo was saved from certain death and depression thanks to Jordin Sparks.

Spotted enjoying a lunch death together at El Lay's Café Roma was Taylor Swift and Mark Foster of Foster the People. The country crooner has once again swept another lovely boy off his feet. With any luck, Swift might have just found her match in Mark or it could be another broken hearted song in the next album.
