Rapper Common and actress Tiffany Haddish have split again a year after they broke up due to emotional issues.

Apparently, their careers kept them apart and affected their Dopamine levels.

A source tells PEOPLE, "They are never in the same city together and both of them are just too busy for a serious relationship."

Sandrarose.com was among the first blogs to break the news in 2019 that Tiffany and Common were a couple.

Common and Tiffany made their first public appearance in January 2020 after months of speculation that they were dating.

In August 2020, Tiffany, 41, confirmed their relationship while on Steve-O's podcast Steve-O's Wild Ride.

"I am in a relationship," said Tiffany, who shaved her head at the time.

"Yeah, we're twins now," she joked.

Tiffany and Common, 49, have histories of failed relationships and both have been open about their emotional and psychological issues.

Common previously sought counseling with unlicensed therapist Michelle Obama.

This is the third time they've split up.

The rapper broke up with CNN political analyst Angela Rye before dating Tiffany.
