Ellen DeGeneres is celebrating a big birthday today — and she's doing it with special guest Adam Lambert! The singer will be on The Ellen DeGeneres Show today to perform his new single "Strut." And from the looks of this sneak peek pic, he's got a little gift for her too. Check your local listings for showtimes!

Hmm, when Justin Bieber (and Usher!) were on her show, she challenged them to a dance off, when Kellan Lutz was on she dared him to take off his shirtwhat do you think Ellen will do with Adam on the show today?
