The 30-year-old actress was not seen with her fiance, Egor Tarabasov, but she was still wearing her green engagement ring -- only it was on her other hand.
Lindsay -- sporting a printed one-piece -- was spotted on a yacht with a bikini-clad friend on Sunday afternoon. The two held hands as they attempted to jump off the boat.
The Mean Girls star was also seen at the bar and lounge, Phi Beach, with pal Hofit Golan. It was here that Lindsay nearly had a wardrobe malfunction in her skimpy black top.
Golan spoke to ET about her famous friend's relationship status. "She’s not been speaking to anyone, including her family. She’s been on a total timeout. So whatever interviews or comments being given out by anyone but her are pure speculation," she explained. "That I can confirm to you. Lindsay hasn’t even had her phone with her, except for taking some private photos."
Golan added, "She’s enjoying a lovely holiday and some downtime now in Europe with her girlfriends. She’s working her matter out privately, as she’s stated. Sometimes the best therapy is a pause."
Meanwhile, Dina Lohan, has been battling a health scare. A source close to the actress' mother tells ET that Dina's been in different hospitals over the past few weeks now. "She is going through testing to figure out what is wrong," the source says. "They do not have any answers yet as they wait for test results to come back."
The source also insists that reports of Dina having cancer are speculative at this time.
Dina's health issues only adds to the recent drama Lindsay has been facing. Last week, in a flurry of now deleted social media posts, she accused her fiance of "not coming home" and posted a video of him with mutual friend, fashion designer Dasha Pashevkina.
Pashevkina opened up to ET about Lindsay's rant, saying, "I felt very violated after she publicly accused me of something which is a complete lie and displayed my private information for the whole world to see."
