Tyra Banks is pulling an Oprah — she's leaving her own talk show!

The Tyra Show will end after its fifth season, the former model announced in an open letter to fans on her web site.

"Most times, a show leaves the air because not many people are watching. Well, you all ARE watching, in record numbers. You must know this love and support is always felt by me and it's given me the courage to take more exciting steps in my life. So I thank you for that."

Tyra said she plans make movies and continue as host of America's Next Top Model. She also promised new digital projects, but wouldn't give details.

The letter also paid homage to Oprah who recently announced she was leaving daytime TV in 2011. "We will all miss her show so much. And to you Oprah: You have had, and continue to have, such an amazing impact on me. I salute you."

Tyra also thanked her fans saying, "I've been loving having fun, coming into your living rooms, bedrooms, hair salons for the past five years."
