UPDATE 9:21 a.m. EST: Seacrest confirmed the news on Twitter.
UPDATE May 1, 8:35 a.m. EST: Ryan Seacrest reportedly is Ripa's new co-host.
ORIGINAL STORY: Kelly Ripa tweeted Sunday, hinting that she will reveal her new "Live" co-host during Monday's show.
"We're going to need a bigger mug. #TuneInToLive #BigAnnouncement #LiveKellyCohost," she tweeted. In the video, Ripa is holding a mug that reads "Live" with "Kelly & ?"
“Tune in tomorrow," Ripa said after taking a sip. "Trust me!"
Ripa has been searching for a new co-host since Michael Strahan left for "Good Morning America" last year. The news of Strahan's departure from the show took viewers and Ripa by surprise.
Strahan reportedly told her about his career move less than an hour before it was leaked to the press, according to CNN.
"Apologies have been made, and the best thing to come out of all of this is that our parent company has assured me that 'Live' is a priority," Ripa said after taking several days away from the show.
Since Strahan's departure, Ripa has entertained a slew of fill-in celebrity hosts including Anderson Cooper, Jimmy Kimmel and Andy Cohen.
Last year, Ripa opened up to People about finding the right co-host.
“You want somebody working there who’s comfortable working there," she told People. "That’s how you figure it’s like a puzzle. It’s very much like an equation, an algorithm."
