Kelly Ripa's new 'Live' co-host is Ryan Seacrest

Kelly Ripa has a new co-host: Ryan Seacrest.

Nearly one year after the departure of former co-host Michael Strahan, Ripa has a new partner for her morning talk show.

Seacrest was announced as Ripa's new co-host on the ABC show Monday morning.

Before Seacrest came on stage, Ripa took a moment to thank her fans and her temporary “Live” co-hosts.

“Today, the next chapter of the ‘Live’ story is about to be written,” she said ahead of the announcement.

Numerous celebrities have filled in as co-hosts with Ripa over the past year, including Jerry O'Connell, Fred Savage and Andy Cohen.

“Thanks is not a big enough word but they took time out of their busy schedules and out of their day jobs… and they are part of the ‘Live’ family forever.”

Ripa said the big TV news came on the same day as her 21st wedding anniversary.

“It’s been funny because Kelly and I were friends,” Seacrest said. “We’ve known each other for a long time… and I couldn’t be more excited to be here with you.”

Ripa teased her fans with a video posted to Twitter on Sunday afternoon in which she took a sip from a "Live with Kelly" mug that also included a question mark. She said in the video, "Tune in tomorrow. Trust me."

The show said it's "growing to two" on Twitter. Another post had "announce co-host" on Ripa's "to do" list.

News of Strahan's exit for "Good Morning America" last May led Ripa to skip the show for two days in protest of the way the situation was handled.

Numerous celebrities have filled in as co-hosts with Ripa over the past year, including Jerry O'Connell, Fred Savage and Andy Cohen.
