It's tough to believe that Katie Holmes is the mom of a 15-year-old daughter. Yes, Suri Cruise, the boy of two well known parents, Holmes and Tom Cruise, is now a full-blown teenager. Suri has mostly stayed out of the general public eye, so it's surprising to check out photos from her childhood on social media. Yet Holmes is celebrating she daughter's 15th birthday by sharing some never-before-seen photos.

“Happy 15th birthday Sweetheart! i love you!!!!!!!! ❤️
