Billy Baldwin is heading to Gossip Girl, but he’s not entirely comfortable with his new role – as Serena van der Woodsen’s dad.

“So you’re gonna go play Blake Lively’s dad on Gossip Girl?’” Alec Baldwin asked his younger brother on the Screen Actors Guild Awards red carpet after taking over the Access Hollywood microphone from Access‘ own Shaun Robinson.

“Ooh, that hurt,” Billy said, referring to his brother’s question. “Three years ago I would have been playing the older man in her life and now, all of a sudden, I’m playing her dad.”

And Alec stuck it to his 36-year-old brother, who was last seen on TV as the politico brother on ABC’s Dirty Sexy Money.

“It seems like yesterday you’d be kissing Blake Lively. Now you’re trying to prevent other men from kissing Blake Lively,” Alec said, turning the knife a little more.

“I would’ve been Blake Lively’s lollipop three years ago,” Billy sighed. “Now I’m Grandpa.”
