Lady Gaga broke one of her personal rules to offer a little support to her friend Tamar Braxton.
Braxton released her new single "Love & War" on Thursday, receiving an extra promotional push from Lady Gaga through a tweet the singer sent to her fans.
After just one day on iTunes, the single claimed the top spot on the U.S. chart -- beating out Rihanna and Taylor Swift during it's ascent. Tamar performed the track during an episode of her television show "Tamar & Vince" and teased an acapella version of the track during an interview with ABC News Radio.
Tamar Braxton rose to fame through the hit WE reality show "Braxton Family Values." It followed the interactions of her and her four sisters, including R&B legend Toni Braxton. Tamar released her debut album "Tamar" in "2000," but according to Billboard, the album never charted.
Tamar was shocked by the single's instant success, telling Essecnce.com it surpassed her expectations.
"I definitely did not expect this kind of response," said Braxton. "The single came out [yesterday], and it's number one!"
Braxton's album is scheduled to be released in February.
