"The Price is Right'' is planning a milestone birthday celebration for former host Bob Barker.

Barker will celebrate his 90th birthday with an appearance on the game show in December. He retired as host in 2007 after 35 years with "The Price is Right.''

The show also will pay tribute to Barker's longtime animal activism by featuring pet adoptions during the week of December 9th through the 13th.

Barker will be on the show on his birthday, December 12th, and will reportedly present a special showcase to mark the occasion.

"The Price is Right,'' with current host Drew Carey, airs weekdays.
