Miley Cyrus and Selena Gomez have a few things in common. Apart from being former Disney stars and becoming the brightest pop stars of this age, Cyrus and Gomez share a connection with another gal pal. Both Cyrus and Gomez are BFF's to "X-Factor's" Demi Lovato. Yet, who is the better BFF for Lovato?

Demi Lovato and Selena Gomez have been friends long before making it to their respective shows on Disney. The two BFFs had first starred on Barney together making them the toughest friendship to ever survive the jungle that is Hollywood. Despite the fights here and rumours there, the "Semi" duo remains perfectly strong.

"I grew up with Demi, I've known her since I was seven...we've had our distance and we've had our moments, but she's one person that I will always love and she'll always have a place in my heart," stated Gomez.

Lovato had also great things to say about Selena during her dark days in rehab. Aside from Nick Jonas, it was Selena Gomez who helped Demi get through her rehabilitation.

"Thankfully my family and friends supported me in rehab and everything I went through. Nick especially & Selena ..she called me crying while I was in rehab and she was very worried," explained Lovato, adding, "Hey! I should be crying! It's okay.' She was very generous and provided that we were getting closer."

Selena Gomez however isn't the only BFF Demi has. Lovato is also good friends with former-Disney star, Miley Cyrus. Like "Semi", Miley and Demi's coined name "Memi" is also trending on Twitter. Apart from supporting Gomez in her career, Lovato also played a big part in Cyrus' comeback in the music scene.

In a fan tweet, Cyrus answered a question regarding Demi Lovato. As expected, Cyrus' answer proved she's still great friends with Lovato.

"Do you miss the Demi? And keep in touch with her? I love you and I am very proud of you! #AskMiley 2," tweeted user SwaagDiley to which Miley responded with, "DON'T GOTTA MISS HER! SHE IS ONE OF THE MOST SUPPORTIVE PEOPLE IN MY LIFE =] SHE WAS MY FIRST CALL THIS MORNING B4 #WECANTSTOP."

Both Selena Gomez and Miley Cyrus prove their supportive and loving best friends. Yet, who between them is the best BFF Demi Lovato could ever have?
