To celebrate Father's Day, we're pitting 16 sexy celebrity dads against each other for the title of Hottest Dad in Hollywood. Not only are these men easy on the eyes, but they are doting fathers who make our hearts melt when we see them out and about with their kids. While it wasn't easy to narrow our list to just 16 (we apologize if some of your faves didn't make the cut), we did our best to include the cream of the crop pops. Help omg! determine who is the hottest dad of them all!
(8) Usher: The sexy "Love in This Club" crooner, 34, is certainly a charmer! Though he often sings about romancing the ladies, what he loves most are his two sons with ex-wife Tameka Foster, 5-year-old Usher V and Naviyd, 4. In fact, he fought Foster for primary custody of the boys in a bitter court battle last year. Now a single dad, the "Voice" coach brags about his kids like any proud parent, even recently posting a photo of little Usher happily showing off the hole in his mouth after losing his first tooth. Too cute!
(9) Ryan Phillippe: Ryan Phillippe is such a devoted pops that he goes the extra mile to make sure he stays on good terms with ex-wife Reese Witherspoon. The two (and even Reese's current hubby, Jim Toth, and Ryan's model gal pal, Paulina Slagter) have no problem hanging out together as they cheer on their kids Ava, 13, and Deacon, 9, at soccer games and other school events. The hunky actor, 38, also has a 23-month-old daughter, Kailani, whom he shares with ex-girlfriend Alexis Knapp. Though Kailani was born months after the “Lincoln Lawyer” star and Knapp broke up, he was reportedly present during her birth and remains involved in his youngest child's life.
