Sara Fosterwas misidentified as her sisterErin FosteratVanity Fair’s annual Oscar partyon Sunday night, and (of course!) her response was hilarious.
The Bumble entrepreneur— who wore a sheer, sequin-embellished Dolce & Gabbana gown, Gianvito Rossi silver metallic platforms, a Dolce & Gabanna beaded headband and a black velvet clutch on the red carpet — documented the entire mishap onInstagram, posting a pair of photos on her main feed and several screenshots on her Instagram Story.
Social media influencerStephanie Shepherd(Kim Kardashian West’sformer assistant) played along with the joke: “Erin you look gorge! So good seeing you last night!” she wrote in the comment section.
“Perfection,”Jessica Mulroney, a stylist and close friend ofMeghan Markle, added.
Sara then proceeded to call out several news outlets who also misidentified her in their Oscars coverage, includingDaily Mail, who published a snap of “Erin” “chowing down” on a burger while chatting withLeslie Odom Jr.,(the post has since been corrected).
“I guess considering there were multiple articles saying that I was marrying Simon this is not so bad …” Sara wrote over the screenshottedDaily Mailpost.
The Barely Famous reality star (the daughter ofmusician David Foster) also shared screenshots of Direct Messages from followers informing her thatE! NewsandVoguehad also mistaken her for her sister.
“I think it’s time to get my real estate license…” she joked, adding, “I’m dead in this town.”
Erin — also famous for her witty sense of humor — shared the same Getty Images screenshot on her own Instagram feed and made a lighthearted jab at her sister in the caption: “What the hell, I was home in sweats not being desperate and Sara hit up parties like a sad mom, and took me down with her.”

“At least I looked great,” Erin quipped.
Despite their public banter, Sara showednothing but love and support for Erinon her wedding day a few months ago.
“We’re so happy for Erin,” Sara told PEOPLE after theNew Year’s Eve ceremony.
Erin (who married businessmanSimon Tikhmanafter one year of dating) said she and her husband are taking the time to enjoy newlywed life — which she said doesn’t feel much different than their relationship before.
“I think it’s different for everyone because some people say they don’t feel any difference. It depends how long you’ve been together and what your relationship was like before. Simon and I have only been together a year and a half altogether, so it moved so fast that all of a sudden we’re like, ‘Holy s—, we’re married,’” she says. “It feels really nice and it feels safe and cozy that I have a husband. Like I have a person keeping me safe from the world, you know?”
