"It's not hard to take a beautiful picture of this magical creature. But I thought this one was special," he wrote about a hazy picture of Jenna.
He followed up the sweet post with another stunning pic of the 35-year-old dancer/actress, giving her credit for his incredible career success.
"If it wasn't for her I would have never even found the path much less stayed on it and not flown off in flaming truck of dynamite singing 'Devil Went Down to Georgia,'" he joked. "To my light. I love you."

Although this, of course, isn't the first time the gorgeous pair -- who met while filming 2006's Step Up -- has proven themselves to be one of our most favorite Hollywood couples. Earlier this month, the two went head-to-head in the most epic Lip Sync Battle episode ever, with Jenna killing her Magic Mike-inspired performance of Ginuwine's "Pony," while Channing brought out the big guns when none other than Beyonce came out for his rendition of "Run the World (Girls)."
"We had a nice fun adventure on my birthday," Jenna shared. "We rode a motorcycle up and down the coast. That was really fun. Scary and fun. And it was a nice surprise. [Channing's] always really good at surprises."
