After 12 years and 22 seasons, Tyra Banks' "America's Next Top Model" is finally coming to an end.

Banks, who host and produce the show, announced the modeling competition show's ending on Instagram Wednesday when she posted a photo of the number 22 -- emphasizing that the current season will be the final one -- and a very long, sorta heartfelt message.

"Yeah, I truly believe it's time," the supermodel, who has been the face and co-creator of the show for more than a decade, wrote on Instagram. "Our diehard fans know we've expanded the definition of beauty, presented what Flawsome is, tooched and booched and boom boom boomed, shown the world how to show their neck, rocked couture/catalogue/commercial poses, have found our (and your) light, strutted countless runways, gone on tons of go-sees, added guys to the girls mix, and have traveled around the globe and back again. Yeah, it's time. It really is."

The show, which first premiered in 2003 on UPN, was really popular during its first few seasons. It even ranked as one of the Network's most viewed shows before it was moved to The CW after UPN merged with The WB in 2006, becoming the first series to debut on the network, The EW reported. Despite its continued popularity, the series has slowly and consistently lost its steam after this move.

"'America's Next Top Model' was a successful franchise for two networks, first at UPN and then The CW, and it became not just a ratings hit, but a global pop culture phenomenon," CW President Mark Pedowitz said in a statement. "I want to thank Tyra and Ken for all their years of success in establishing a show that was not just popular in the U.S., but all across the world."

The show will air its series finale on Dec. 4.
