Aubrey Plaza brought a surprise dose of star power on the second-to-last episode of The Last Show with Stephen Colbert on Wednesday night .

Plaza's pregnancy revealed

The 41-year-old actress looked absolutely stunning as she made a grand entrance while showing off her heavily pregnant figure.

Plaza poked fun at her prominent baby bump with her characteristic deadpan humor after she revealed last month that she's expecting her first child with Girls star Christopher Abbott.

Colbert's penultimate episode

She was helping to send off Colbert after CBS announced that it would be canceling The Late Show amid repeated criticism over Colbert's jokes from President Donald Trump and its parent company Paramount's attempt to ink a merger deal with Skydance Media.

Plaza was one of the celebrity guests in an episode packed with them, including Robert De Niro, James Taylor, Ben Stiller, Billy Crystal, Martha Stewart, Josh Brolin, Amy Sedaris and more.

Each of the celebrity guests got to take a turn behind Colbert's desk to ask him one question, while he moved over to the first chair to answer.

Plaza's hilarious question

But to avoid getting too somber for the 62-year-old late-night host's penultimate episode, Plaza and the rest of the stars asked him hilariously inconsequential questions.

After guest announcer John Dickerson announced Plaza's name, the audience erupted into cheers as she sped out while wearing a lovely navy dress that downplayed her baby bump,which was also partially hidden behind her blue notecard.

After she took a seat, Colbert asked her how things were going, and Plaza shifted awkwardly in her seat and looked down.

'Um, everything's going normal here!' she said in a sing-song tone with a nervous grin.

'Nothing weird...'

She turned on a dime and joked, 'My water broke backstage.

They said it was gonna take a couple hours, so I can still do this.'

Plaza's pregnancy a surprise

The White Lotus actress's fans were shocked last month by reports that Plaza was expecting her first child with Abbott, 40.

The baby, whose gender has not been revealed, is due in the fall.

'It was a beautiful surprise after an emotional year,' a source told People.

The couple , who previously starred on Broadway together before falling in love, are said to be feeling 'very blessed.'

The couple, whose relationship had not been previously reported, first worked together in 2019 on the indie psychological drama Black Bear, in which both actors played dual roles as actors and directors trying to shoot a film in an eerie, isolated lake house.
