It's Ellen's birthday show!

She's celebrating with one of her favorite people on the planet, JIMMY KIMMEL! Every time he's here, Jimmy changes the game. He's rolled around in a bubble wrap suit, and saved Ellen from an attacking panda! There's no telling what he will have in store for her birthday when he co-hosts the show!

And one of the funniest ladies around, MELISSA MCCARTHY is here! She starred in Ellen's favorite movie of the year, "Bridesmaids" and always makes Ellen laugh! It's going to be a very special birthday surprise!

Plus, the legendary band, EARTH WIND AND FIRE are here to make Ellen's birthday wish come true and perform on her show!
