Miley Cyrus' boobs weren't the only surprising thing on the red carpet at the 30th Annual Rock and Roll Hall of Fame Induction Ceremony over the weekend—Karen O also debuted her baby bump!

The Yeah Yeah Yeahs singer showed off her bun in the oven in a black fitted mini dress shortly before performing in honor of the late Lou Reed.

The 36-year-old didn't speak about the exciting pregnancy news, but her ear-to-ear grin and glow seemed to say it all.

Karen O is married to director Barnaby Clay, who has worked with the Yeah Yeah Yeahs as well as Depeche Mode, Gnarls Barkley and Mick Rock.

And while the mommy-to-be released a solo album last year dubbed Crush Songs on The Strokes' Julian Casablancas' Cult Records label, she told NME recently that she and her band are taking a bit of time off in 2015.

"We are on a bit of hiatus at the moment, so nothing yet. We have to wait to get the urge, get that itch. The time needs to be right and we're OK waiting for that, I think," she explained, adding that when the group does decide to get back together for new material "it'll be like muscle memory, this unspoken thing between the three of us where it all just…locks in."

We'd bet that a new baby will bring about tons of inspiration for new music in the future, right?

Either way, congratulations to Karen O and her hubby on their future arrival!
