Jenna Dewan-Tatum and husband Channing Tatum aren't exactly strangers to cutest-couple lists: Right here on Glamour.com, we've recently compiled a list of 21 times they stole our hearts and 11 times they were relationship goals. After 11 years of being together and 7 years of marriage, they are still complete goofballs around each other—and Channing even removes Jenna's toe nail polish.

Too. Much.

But it's also obvious that the Tatums know how to show their love on birthdays: Jenna went all-out for her hubby's 36th birthday back in April by giving him a rescue horse named Cajun.

So given the evidence above, it's not exactly a surprise that Channing posted the most adorable Instagram for his wife's 36th birthday yesterday. He wrote, "I'm not sure if this woman is my Rainbow or my pot of gold but I'm lucky either way happy birthday cake baby!" The photo is of them under a rainbow and, yes, he calls her Cake. Could it get any cuter?

Those two.
