'Is that me or my mom?' Gwyneth Paltrow shares throwback pic of Blythe Danner

Gwyneth Paltrow made her Instagram followers do a double take Thursday night, when she shared a throwback shot to show the uncanny resemblance she shares with her mom, Blythe Danner.

The actress reposted an image surfaced by Instagram user doncohb, which shows Danner on a 1972 episode of the classic TV series "Columbo."

"This is weird. #isthatmeormymom," Paltrow, 42, captioned the photo of her mother, who would have been 29 when it was taken.

Paltrow and Danner aren't the only famous mother-daughter duo with nearly identical features. Earlier this week, Rumer Willis shared a shot of her and her mom, Demi Moore, looking like twins.
