Lindsay Lohan may not be feeling well, but she still wants to look good. The Life Travelers actress stripped down to a barely there Calvin Klein thong on Saturday, Jan. 24.

"#mycalvins are helping me fight off my chikungunya hehe," the 28-year-old captioned an Instagram bathroom pic. The Mean Girls alum wore nothing but the underwear and a long-sleeve crop top, which showed off her very slim midsection and toned legs.

Thank You!

Last month, Lohan revealed that she contracted the untreatable virus Chikungunya while vacationing on the South Pacific Island of Bora Bora. The virus is transmitted by mosquitos and can cause joint pain, fatigue, and fever.

"Before I got chikungunya. Use Big spray please God bless," she tweeted at the time. "Being sick is no fun. But happy new year everyone. Be safe. Love all."
