Meanwhile, the birthday girl also took to Instagram to thank her fans for the overflowing wishes.

"Kisses for all of you!! THANK YOU for my happy birthday wishes!!!!" she wrote. "I can't possibly thank you all individually, but please know I love you all and words can't explain how grateful I am for your love and support always."

The pair first met while filming their 2006 hit Step Up, tied the knot in 2009, and welcomed daughter Everly in 2013. And it looks like their love is still going strong!
