Ke$ha Talks to Ryan Seacrest, Dishes on Writing Music for Britney

She's a bona fide pop star in her own right, but, as she spoke with Ryan Seacrest earlier today (April 4), Ke$ha gushed that she has written music for pop icon Britney Spears.

Having witten the hit track "Till The World Ends" for Spears, the "TiK ToK" singer told On Air with Ryan Seacrest: "She's a pop icon. The biggest pop female icon, so to be able to write a  song for her is absolutely incredible an the fact that she liked it and connected with the words I wrote was kind of unbelievable. I was nerding out."

The 24-year-old also announced her plans to add shows to her sold-out tour, as she'll be hitting the road with "LMFAO" and "Spank Rock" from July through September.

Last, but not least, Ke$ha was sure to mention the launch of her brand new fan site, KeshasFamily.com, where her faithful followers can find plenty of Ke$ha related happenings.

The "Blah Blah Blah" songstress will be making a guest appearance on an upcoming episode of Nickelodeon's "Victorious" along with her younger brother Louie Sebert.

The storyline follows Tori (Victoria Justice) and her friends as they try to win tickets to see Ke$ha live in concert.

Miss Justice told press, "It's a private concert, and yeah, I will say that the costumes are awesome and there's definitely lots of glitter. It was really fun to film. It's the first time on my show that we've had a successful radio artist perform on the show. Ke$ha's kind of edgier, and I think that it's cool to bring that element to the show."

Making the most of her time in Las Vegas, Britney Spears was spotted at a performance of "The Lion King" yesterday (April 3).

The "Hold It Against Me" songstress treated her two sons Jayden James and Sean Preston to the show, playing at Mandalay Bay.

After the final curtain, Britney and her boys posed for photographs with actors Kissy Simmons, Derrick Williams, and Ntsepa Pitjeng.
