The summer heat is on and what better way to heat things up even more than summer romances? Hollywood may be in a rut with divorces and splits happening here and there but these true-blue couples are enough to turn fans' frowns upside down. Check out summer's most sizzling couples.

First up is the newest in the bunch, Lily Collins and Jamie Campbell Bower. Both A-list celebs have had their separate splits. Lily Collins called it quits with Zac Efron just recently while Jamie Campbell Bower ended his two year engagement with "Harry Potter" star, Bonnie Wright. "Heartbroken" is the least appropriate word to describe these two. Just yesterday, Lily Collins and Jamie Campbell Bower were spotted holding hands right after grabbing a cup of Starbucks coffee.

Collins' ex-flame, Zac Efron seems to be getting along fine as well. The "High School Musical" hunk was seen cozying up to Swedish model, Alexandra Storm. The rumored couple was spotted together at Café de Paris in Monte Carlo.

Enough to shut the break-up rumors, the "Jelena" duo hit Tokyo together where the couple shared an adorable photo on Facebook. Flying over a hundred miles, Selena Gomez joined Bieber in Tokyo who was busy preparing for his Tokyo "Believe" tour.

Country crooner, Taylor Swift, is one to make "swift" summer moves. Last month, the singer was spotted enjoying a lunch date with "Foster the People's" front man, Mark Foster. However, it appears as if Foster is old news. On July 4th, Swift was spotted walking along the beach with Patrick Schwarzenegger, Arnold Schwarzenegger's son. A photo of the two hugging has also been widely spread on various websites. It's proof enough that "something swift" is happening.

No matter how hard Demi Lovato denies the dating rumors with One Direction's Niall Horan, fans still believe the "Skype" virtual dates have led to something. The two have been continuously in contact with each other for quite a while. It's enough to say that Niall Horan and Demi Lovato are indeed a couple.

"The Amazing Spiderman" had debut an amazing box-office record. Thanks to the film, fans have fallen even more in love with the on screen and off screen couple, Andrew Garfield and Emma Stone. The couple's incredibly hilarious and quirky interviews and photo shoots for Vogue are enough to make anyone believe "nerdy" love lasts.

Last but not the least would be the recently engaged and soon-to-wed couple, Miley Cyrus and Liam Hemsworth. Despite the constant criticism and feedback of a few relationship advice columnists, these two have stuck like glue to each other and their decision to wed. If anything, Miley & Liam appear to be more in love than before.
