Hollywood's Celebrity BFFs: From Nina Dobrev and Julianne Hough to Selena Gomez and Taylor Swift [PHOTOS]

"Selenators" and "Lovatics" are still hooked on the idea that Selena Gomez and Demi Lovato are BFFs until today. Well, these two former Disney stars may claim they're still on each other's hearts and minds, but actions speak a hell lot better than words. Obviously, Selena Gomez replaced Demi Lovato with Taylor Swift as her BFF. Who else in Hollywood has a new celebrity BFF that they've been flaunting around?

"Vampire Diaries" star Nina Dobrev may have suffered from a broken heart early in June, but BFF Julianne Hough was present to mend it. The two shared countless photos of them braiding each other's' hair on the beach to their fun-in-the-sun Instagram posts. Aside from baring their bikini bottoms, Julianne and Nina enjoyed the courtside action as well.

"Semi" may be forever in the hearts of fans but that isn't likely the case for Selena Gomez who spent most of her time hanging out with new celebrity BFF, Taylor Swift. Last week, Gomez celebrated a week long birthday and fans had expected BFF Demi Lovato to arrive. However, the "X-Factor" judge was nowhere to be seen. Country crooner Taylor Swift, however, was present during the first celebration. Proving that they're BFFs, Taylor posted a sweet Twitter message along with a photo of her and Selena on Twitter. Lovato, on the other hand, didn't.

Of course, while Selena Gomez is BFFs with Taylor Swift, Demi Lovato is BFFs with former Disney star Miley Cyrus. Lovato may care the least about Gomez's partying, but she obviously cares a lot about Miley Cyrus who "can't stop" twerking and partying.

"She knows how I feel about the whole partying thing," said Lovato in an interview with MTV News, adding, "I love her to death and I'm always like, 'Just be careful.'"

Another friendship that brewed by the beach is that of Rihanna and Cara Delevingne. Rita Ora, Cara's "wifey," might not have been present, but Rihanna was one quick replacement. Photos of Rihanna grabbing Cara's bum went viral on a few social networking sites. To say the least, these two beauties are tight.
