The long-awaited Britney Spears tribute episode aired on 'Glee' Tuesday night, and Britney made cameos in the 'Me Against the Music' video with Heather Morris and later in a cheerleading uniform for a dream sequence. Pics of Heather in her Britney costumes here.
Britney live-tweeted the episode as she watched, complimenting all the cast members as they appeared.
"Awww Heather Morris is sooo cute! Brittany S Pearce. Ha! She was so fun to work with and was really sweet in person," she wrote. She also called Jane Lynch "hilarious and scary" and John Stamos "still hot."WATCH:
