Justin Bieber's mom may be Team Selena Gomez.

Last week, in celebration of Gomez's 24th birthday, Pattie Mallette shared a series of tweets to the singer and shockingly favorited a tweet about the potential return of "Jelena."

Following her sweet birthday messages for Gomez, Mallette favorited the tweet below from a fan who wanted to hear about the future reunion of Bieber and Gomez.

Gomez and Bieber dated from 2010 to 2012 and in the years since their split, the singers have kept in close contact. However, at this point, it has been months since they've been seen together.

In December of last year, Gomez and Bieber were seen taking a stroll in Beverly Hills, Calif. and around the same time, Bieber was spotted singing "My Girl" to his ex-girlfriend. Then, in March of this year, Gomez showed her support for Bieber's career when she attended one of his Purpose World Tour shows in Los Angeles.

Since March, Bieber and Gomez haven't been seen together at all and Bieber has made it clear that his focus is elsewhere with his many outings with other women, including Hailey Baldwin, Chantel Jeffries and Kourtney Kardashian.
