Kelly Ripa and Fred Savage fuel frontrunner co-host rumors on 'Live!': 'Welcome home'

Fred Savage is feeling "very comfortable" on the Live! With Kelly stage.

The 40-year-old actor was Kelly Ripa's Live! co-host on Wednesday, when the two displayed their obvious chemistry. Ripa greeted Savage -- who has successfully co-hosted Live! before -- with a "welcome home," to which he tellingly replied, "I feel very comfortable now."

He also made it clear he enjoys the gig, when the former Wonder Years star told a story about what his young daughter Lily bought him for his recent 40th birthday. Savage said that when the salesman asked what her dad likes, she adorably replied, "Well, he really likes co-hosting with Kelly."

Earlier this month, a source told ET that Savage is definitely interested in becoming Ripa's permanent Live! co-host, though he's reluctant to relocate his wife, Jennifer, and their three young kids -- Oliver, Lily, and Auggie -- to New York City. Savage is booked to co-host the show for the rest of the week.

Savage was a natural on Live! on Wednesday, interviewing both Blake Lively and Mr. Robot star Rami Malek.

He also gamely ate stinky tofu during a Bizarre Foods segment with Andrew Zimmern.
