Jeopardy! host Mayim Bialik shows off cleavage in plunging dress in major glam makeover

JEOPARDY! host Mayim Bialik has scored a massive makeover, showing off some cleavage while in a plunging dress and glasses-free for a new steamy sitcom photoshoot.

She went full glam for promo pics ahead of the September 29th premiere of Call Me Kat.

Mayim, 46, has revealed the absolutely foxxy new look ahead of Season 3 of her Fox sitcom, premiering next Thursday.

In the sultry snaps, she stared down the camera with a smoky eye, a daring criss-cross dress - and tossed one leg over the other showing plenty of skin.

The blazer-clad, modestly dressed Mayim fans have gotten to know on Jeopardy! - which dual host Ken Jennings, 48, is handling until January - was not on the board.

Instead, she simply stunned ahead of her new sitcom season with cropped hair too - and she's hinted it may stay this way when she's back on the game show.

Mayim went glasses-free for her first-ever interview with dual host Ken in August.

For their special joint appearance talking about the challenges of replacing Alex Trebek, Mayim wore a chocolate-colored brown designer blouse and a black jacket over her top.

Her hair was straightened and flowed down to her shoulders - most notably, her eyeglasses were gone, giving fans a clear view of her TV set-ready makeup.

Mayim even joked to the alum-turned co-host that on tape days going forward, she's upping her fashion game like we're now seeing.

“I come in looking like Ken and I come out looking like this,” she hilariously dissed on the weekly podcast Inside Jeopardy!.

Ken - who typically slicks his hair back, less shaggy than when he was a contestant - was quite surprised.

He replied with a laugh sitting next to her: "Like, looking like me right now?"

As TV line earlier detailed: "[Last season] Kat [the main character who is played by Mayim] decided to take some time for herself and head to Paris."

"In the Season 3 premiere, we find Kat returning home, and she’s feeling particularly chatty about her travels abroad.

"Can you guess who is seated next to her on the flight? None other than Jeopardy!‘s winningest contestant, Ken (playing himself)."

'CALL ME KEN JENNINGS'

Mayim indeed shared that the first episode of Season 3 is an all-out host homage, as Ken is making quite the cameo.

Mayim revealed on their August joint podcast appearance: "Ken very very graciously appears in our season opener of Call Me Kat.

"It was exciting for everyone - everbody freaked out when they heard Ken was coming.

"The episode is called, 'Call Me Ken Jennings,'" she sweetly shared.

“That’s my request” Ken joked.

Mayim said: “It was really fun and very meta to have my character to meet Ken Jennings. You're very funny and you did a great job”

“A sitcom set is very different from what you do here [on Jeopardy!] but everyone was very tickled by you and you were hilarious.”

“Your continuity was really good because we did it a few times and it was really fun.”

Ken humbly said: "It's a good bit, Mayim carries it because she's kind of playing a chatty passenger and I'm playing grumpy Ken myself" which he joked was "It was very easy to play - method acting."

The art-imitates life joint appearance will happen in just days, when the 30-minute sitcom premieres.

It's especially momentous since the two hosts don't present Jeopardy! together.

When Mayim shared a rare on-set photo to tease the sweet project sitting together with the 74-time Jeopardy! G.O.A.T on a sofa - she was glasses-free for the first major time on social media.
