Justin Bieber and Selena Gomez are rumored to be "hooking up" again and could be headed towards yet another attempt at reconciliation in their on-again, off-again relationship.

According to HollywoodLife, In Touch magazine reports their latest dalliances started around the time Bieber began celebrating his 21st birthday in March and presumably have continued. Although Bieber has recently been publicly seen with both Kendall Jenner and Shanina Shaik, the website adds he and 22-year-old Gomez appear committed to seeing if they can make things work out.

"Justin had secretly been hooking up with Selena since his birthday," a source added. "They wanted to see if they could get back to a good place." The website notes the couple's latest attempt at rekindling their relationship comes just weeks after Gomez ended her short-lived romance with DJ Zedd.

With Bieber apparently back in the fold, it seems now is the season for repairing once tattered relationships for Gomez. The "I Want You to Know" singer is also rumored to have recently put aside her differences with Kylie Jenner and rekindled their past friendship.

Gomez and Jenner had a falling out not long ago after rumors flew she had hooked up with Bieber at the 2014 Coachella music festival. Tensions between the two grew even more in recent months when it was alleged her sister, Kendall, had also become romantically involved with him.

Since splitting with Gomez the last time, Bieber has also been romantically linked to several other women, one of the most recent being 19-year-old British model Jayde Pierce, whom he supposedly may have gotten so serious with he had already met her parents, it was reported.

Bieber once vowed that he would win Gomez back even if it meant having to change some of his colorful and controversial ways.
