Claire Danes is expecting her third child with husband Hugh Dancy — but it isn’t good news for all involved!

On Friday’s “The Tonight Show Starring Jimmy Fallon,” Danes, 43, admitted their sons are meh on making room for a third sibling.

Cyrus, 10, is “sort of resigned to it,” she said, noting that when her son Rowan came along, that was already “the worst” for him, initially.

“But Rowan has more to lose,” she said of her 4-year-old. He has more at stake. He was against the idea. “

Hilariously, she reported he said, “Yeah, no, no. It doesn’t appeal to me. It doesn’t appeal to me. I like peace, Mama. “

Rowan came around when she explained that the new baby would need to be educated. “

Rowan met Dancy, 47 on the set for their 2007 film “Evening.” They were wed in 2009.
