Selena Gomez and Justin Bieber are commonly known for their on-off relationship, but once source claims the couple are friends with benefits, PerezHilton.com reports.

"Their relationship is at a bit of a holding pattern... They are pretty much single but will hook up when they are in the same city," the source told the website.

Selena Gomez has confirmed that the couple has split and Justin Bieber has been under the spotlight for his flirting with numerous women.

Justin Bieber plied beautiful Milyn Jensen with McDonald's the night of their alleged one-night stand, the New York Post reports.

Milyn Jensen is largely credited with splitting up the Hollywood couple after her one night stand with Justin Bieber on Dec. 21 at a Los Angeles night club.

The 22-year-old told The Sun that she was introduced to the 19-year-old Bieber by his best friend, rapper Lil Twist, and when the party was over, she said Bieber took her, her best friend and Twist in his custom SUV to a nearby McDonald's where he got "two double cheeseburgers for himself" and he bought his lovely date "some large fries," the New York Post also reports.

But Milyn Jensen isn't the only girl who might have Selena Gomez upset at Justin Bieber.

Ariana Grande posted a photo of Justin Bieber kissing her on the check on Thursday, leaving fans wondering if she's the "Heartbreaker" star's new lover following his relationship with Selena Gomez.

Although Ariana Grande immediately posted a message saying "Everyone, girls are allowed to be friends with guys. I'm a lady. Chill out," and quickly denied the rumors, some say the couple looked a little too intimate in the picture to be friends.

Some celebrity analysts also mention, however, that he is trying to get Selena Gomez jealous or is trying to get her attention.
