Actress jokes that her Calvin Klein underwear is helping her fight off her sickness

Lindsay Lohan is out of the hospital and back in the selfie game!

Just days after the actress was briefly hospitalized in London, the actress decided to lighten things up with a new Instagram post Saturday afternoon.

Wearing Calvin Klein thong underwear and a tight long-sleeve T-shirt, Lohan showed off her thin frame while posing for a selfie in the bathroom.

“#mycalvins are helping me fight off my chikungunya,” she captioned online. “hehe”

Just before New Year’s, Lohan opened up about contracting the virus spread by mosquito bites that can cause rashes, fatigue, muscle pain and other side effects.
