Ashlee Simpson took to social media Thursday to wish husband Evan Ross a happy birthday, sharing a naked photo of the actor in his honor.

"Happy Birthday to the love of my life," Simpson posted to Instagram on Thursday. "Your spirit is truly infectious, and I’m so lucky to spend everyday with you. 33 baby."

The post included a black and white snap of them together and a second of the "She Ball" actor naked while taking a steamy shower.

Ross’ older sister, Tracee Ellis Ross, commented on the photo, "@ashleesimpsonross [laughing emojis] the shower photo."
