Ellen DeGeneres is placing her bets!

The TV host met with pregnant actress Natalie Portman during The Ellen DeGeneres Show on Wednesday, Dec. 6 — and voiced she's sure her baby will be a girl!

"I did three tests on you," Ellen said regarding the gender. "Each one came back that it was a girl."

Natalie previously appeared on the talk show five years ago when she was pregnant with her first child, Aleph. At that time, Ellen also tried to guess the gender of her baby — and ended up being incorrect!

"Want to make a bet?" Ellen asked. Natalie, agreeing, said, "Well, it seems like it would be in my favor since last time you were so, so wrong."
