Rosamund Pike may be keeping mum on the name of her second son (although PEOPLE has learned the boy, born in early December, is named Atom), but she’s fine with a sharing a photo — especially if it involves Rob Lowe!
The handsome actor crossed paths with the Gone Girl star, 36, at the airport and couldn’t resist a quick snap, which he posted Saturday.
“My flight to London was filled with many of my fellows,” Lowe, 50, captioned the photo. “Here’s the fantastic Rosamund Pike with her tiny treasure.”
