Justin Bieber and Hailey Baldwin have been spending a lot of time together this month, but the 18-year-old model is no rebound girl. Bieber insists he's "super single" and Baldwin concurs.

“People are crazy. I’m super single and this is my good friend u would known otherwise,” the 20-year-old pop singer captioned an Instagram photo of him and Baldwin in the back of a car.

The daughter of Stephen Baldwin followed his post with a tweet of her own.

"hope that clarifies everything for everyone :) rumors are silly!" Baldwin wrote.

The two have enjoyed each other's company a lot recently. This past weekend alone they flew to Seattle, hiked at Runyon Canyon Park in Los Angeles and hung out backstage with good friend Kendall Jenner at Chris Brown's concert.

Baldwin also denied the dating rumors after the two were spotted courtside at a Los Angeles Clippers game and having lunch together in Beverly Hills earlier this month.

"I've known him since I was so young -- since I was like 13 -- and we've just been good friends over the years," she told E! News on Dec. 8. "We have just stayed close and there's nothing more to it than that."

Bieber split with his on-again, off-again girlfriend Selena Gomez back in October. The two seem to have parted amicably as Gomez recently told NRJ radio in Norway that she has "so much respect and love for [Bieber]."

She did however give an emotional performance of her hit single "The Heart Wants What It Wants" at the American Music Awards. She opened the song with a recording of her talking about a lost love (most likely Bieber) and then changed the lyrics at the end of the song, simply repeating "I thought you were the one."

Gomez also remains single and revealed in the NRJ interview that she "doesn't even know how to work" the dating app Tinder.
