At a time when Justin Beiber-Selena Gomez relationship is rumored to be over, the singer has taken to Instagram to post a photo of himself with his ex-girlfriend.

The picture shows the 21-year-old singer on an ATV with Selena. His head is seen resting on her back while her hand caresses his leg, reported EOnline.

The social posting from Beiber comes just two weeks after the two were spotted hanging out together in Beverly Hills. The pop star went on to serenade Selena at the Montage Hotel on Nov. 20.

"He was even seen kissing her forehead after his quick performance," an insider told TMZ.

However, it seems Selena Gomez is in no mood to talk about his alleged ex-boyfriend Justin Bieber any more.

In a recent interview with InStyle UK, the 23-year-old singer revealed that she's fed up of replying to questions about her ex-boyfriend Justin Bieber.

"It's really hard because I'm a nice person. I'm just tired of talking about it," confessed Selena, reported Franchise Herald. "I never intended for my life to become a tabloid story."

The magazine also asked the brunette beauty whether or not she'd consider dating Zayn Malik as rumors suggest that the former One Direction member is into her after following her on social networking site Twitter.

"If he had asked me out on a date, I would be seen with him," she said with a smile on her face. "Just kidding, but not kidding."

Malik is currently rumored to be involved with Gomez's friend Gigi Hadid. The singer also revealed that she likes mature men and regrets looking young for her age.

"I feel like I look 16 sometimes, which is a bummer because I would love to date older guys," the singer admitted.

The January issue of InStyle will go on-sale Dec. 3, Thursday.
