'Glee': Watch the 300th Musical Performance (Video)

Amber Riley, Naya Rivera and the Trouble Tones team for the Adele mashup in Tuesday's episode.

Tuesday's Glee will feature a major milestone in the show's history when Naya Rivera and Amber Riley take part in the show's 300th musical performance.

Singing as part of McKinley High's new all-girl glee club, the Trouble Tones, the Adele mash-up of "Rumor Has It"/"Someone Like You" will showcase Mercedes and Santana and be the third time the Fox series has performed an Adele track.

Columbia Records topper Rob Stringer said last month during an event marking the milestone on the Glee set that it was a "happy coincidence" that the label handles both Adele and the music for the hit dramedy, while Riley noted the performance stemmed from a video she was emailed.

Someone emailed me a video of Adele saying she wanted me to sing her song, so I emailed it to Ryan and Brad and I think that's how we got 'Rumor Has It'/'Someone Like You,' " she recalled.
