Seeing as Jessica Simpson has posted Instagram photos where she looks like she's about to get naked with her hubby, this next bit shouldn't come as much of a surprise...

The starlet wished her husband, Eric Johnson, a happy birthday on Instagram yesterday, and she posted the sexy photo above and wrote, "Happy Birthday Eric Johnson!!! Thank you for giving me the sexiest porn star name. Love, your wife, Jessica Johnson." Um, haha? At least she tried...

Earlier this year Jess dished to People that the secret to her happy relationship was "making out," adding, "Don't forget to kiss. It's more intimate sometimes for a lot of people and if you forget that, you forget why you fell in love in the first place. It always begins with a kiss." Actually, she might be onto something there...

Jessica and Eric started dating in May 2010 and got engaged just six months later. In 2014 they got married, and they're proud parents to daughter Maxwell Drew Johnson, born in May 2012, and son Ace Knute, born in 2013.
