9 Celebrity Studs You Didn’t Realize Were So Short Ryan Seacrest 5’8” flickr.com Although not loved by all, Ryan Seacrest has his share of fans. The American Idol host stands at only 5’8” and his love life seems a little suspicious. He is now 41 with no children or wife. In 2010, he did date Julianne Hough for three years, but the two never married. She was most well know for her participation in the TV show Dancing with the Stars. Since 2016 is the final season of American Idol, Seacrest will finally be hanging it up as the host for the once wildly popular TV show. After the first few seasons, the show never really put out any great talent.
