Happy birthday-suit! Chelsea Handler wished her pal Reese Witherspoon a happy birthday on Tuesday, March 22, with a nude mirror selfie.

“Happy Birthday @reesewitherspoon,” the Chelsea Does star, 41, captioned the funny, risqué post, in which she covers her naked self with just her arms.

The former E! host was on hand to help Witherspoon ring in her 40th birthday with an early celebration on Saturday, March 19, at Los Angeles hot spot Warwick. 

The Legally Blonde star — who rented out the entire venue to host a Mardi Gras–themed party for her big day — was also feted by pals including Kate Hudson, Jennifer Aniston, Justin Theroux, Courteney Cox, Matthew McConaughey, Robert Downey Jr., Isla Fisher, Conan O'Brien, Chris Martin, Tobey Maguire and more. Taylor Swift and Keith Urban performed at the party, serenading the actress with the hits “Shake It Off” and “Sweet Home Alabama.”

According to a source, the birthday girl had a blast at her bash and partied until 2 a.m. “She had the best time and didn’t want the night to end,” the insider told Us.
