Sheree Whitfield and NeNe Leakes of The Real Housewives of Atlanta are heating things up this season, and not just on their hit reality show.

Just in time for the holidays, Sheree Whitfield premiered her first ever single, “Who Gon Check Me Boo?,” Sunday night on Andy Cohen’s Watch What Happens Live.

During last night’s show, Glee stars, Lea Michele and Chris Colfer revealed that NeNe Leakes will soon join the cast of the musical comedy as a recurring guest star.

“Who gon check me boo?” is Sheree’s infamous quote from an argument that she had with a party planner during season 2 of The Real Housewives of Atlanta.

In the auto-tuned track, Sheree answers questions about her financial situation and also take jabs at a female, whose name she never mentions.

Lyrics to the song include:

“Before you say anything else to me, go and fix your grill.”

“Saying that your rich, but its just a mirage. Stuntin’ like you a star, you need to quit it girl, stop.”

Many people are saying that the song is directed at Sheree’s ex-friend NeNe, who she has been feuding with throughout the current season of RHOA.

NeNe is clearly not allowing Sheree’s new song to slow her down. She will soon be featured in a recurring guest role as William McKinley High School’s new swim coach, Roz Washington, on Glee.

Last night, after the news of her Glee role was announced, NeNe expressed her overwhelming excitement via Twitter.

“Running through the house screaming Gleeeeee!” she wrote in one of the messages. “Coach Roz Washington is gonna get that Sue Sylvester! I’m so proud of myself.”

NeNe is the first reality star to ever be featured on Glee.

Her character, Roz, is said to appear on both the Grease themed episode as well as the Michael Jackson tribute episode in January.
