Whoops!

Jeffrey Dean Morgan was red-faced after accidentally revealing the gender of his next baby with partner Hilarie Burton on Sunday.

“The Walking Dead” star slipped and told the crowd at a New Jersey “Supernatural” convention he and his longtime love are expecting a baby girl.

A fan caught the awkward moment, which the actor posted on Instagram.

“Whoever took this picture?? Caught a moment… thank you,” Morgan, 51, wrote. “We shall cherish…. I texted @hilarieburton right after I spilled the little girl beans… and, as usual… she was a rockstar. After all these years she’s come to expect me to be a dope… thank god she gets it, and loves me regardless.”

Last week, Morgan and Burton, 35, announced that they’re expecting their second child. The “One Tree Hill” starlet and Morgan have been dating since 2009 and share a son, Augustus, born in March 2010.
