CALEXICO, California - Ke$ha recently performed before a sell out crowd of 42,000, at Calexico's El Tamale Arena.
She sang her biggest hits including "Tik Tok" and the follow up song "Tik Tit Tat" and "Blah Blah Blah" and the follow up song "Ha Ha Ha."
Ke$ha has been quite busy lately appearing on such television shows as Wheel of Fortune, Let's Make A Deal, CSI: Las Vegas, and Cooking Up Cajun Stuff With "Creole" Conchita .
The 23-year-old known as "Glitter Girl" has also appeared on the front covers of such highly respected publications as Women's Wear Daily, Glitter Glam, Glitter Illustrated, and Twitter While You Glitter Monthly.
But Ke$ha says that she has never been more excited than now when she has been given the opportunity to star along with Selena Gomez in Salvo Classacotti's Las Vegas robbery thriller entitled $ $ign$.
The movie is based on the true story of two young cousins who single-handedly managed to hold up three of Las Vegas' leading casinos within a 48-hour period.
Ke$ha stars as Millicent Caboodle who masterminds the plan and convinces her younger cousin Danielle Honeyhouse ($elena) to join her.
Young Selena is quite a busy young lady in her own right. She is the star of the Disney Channel's The Wizards of Waverly Place and has recorded many hit songs.
Two of her biggest hits were recorded with fellow singing sensations and best friends Miley Cyrus and Demi Lovato. Their first collaboration together was "My Skin Is Just Itching To Be Touched," which Selena was told is Paris Hilton's all-time favorite song.
The second Cyrus-Gomez-Lovato production was a song written by Rihanna and titled, "I Can Giggle, And Wiggle, And Fa Shizzle My Nizzle."
