The 30-year-old "Mean Girls" star and the Israeli socialite are currently enjoying a holiday together in Sardinia, Italy, reported Us magazine.
"We've been doing acupuncture, massage, stretching, drinking lots of green juice, exploring caves, fishing, swimming, just doing normal things.
"Lindsay and I have known each other for years and she's a very close friend, she's loyal and an amazing person. It's unfortunate that other people in her life, I'm not going to name names, are confirming she's pregnant, which she's not," Golan said.
Golan also dished on the "Freaky Friday" star's relationship with Tarabasov debunking the rumors that they have broken up.
"This vacation is amazing, it's not a single girls' getaway or a post-breakup vacation. Lindsay is taking a pause in her relationship and joined my friends and I on holiday," she said.
