*”Real Housewives of Atlanta” standout NeNe Leakes made her debut on “Glee” last night, and the show did not “water” down her NeNe-ness one bit.

The reality star played McKinley High swimming coach Roz Washington, a proud Olympic medalist who has no time for “trouty mouth” children testing her patience.

“Sam Evans, I’m coach Roz Washington, and you are one strange looking kid. I’ve never seen lips like that on a white child,” she said.  [Watch the clip below.]

After her appearance aired, NeNe tweeted her fans: “Thanks u all who r tuning n2 Glee & Thanks so much 2 every1 that has tweeted & texted me well wishes! I’m overwhelm wit happiness.”

Leakes also tweeted that her next appearance on “Glee” will air on Feb. 7.

Meanwhile, “Glee’s” all-Michael Jackson episode will air on Tuesday (Jan. 31). View pics from the episode below the NeNe clip.
