When Beverly Hills, 90210 ended in May of 2000, fans squealed as Kelly Taylor finally ended things with Matt (Daniel Cosgrove) for her on-again off-again boyfriend Dylan (Luke Perry). Fourteen years later, star Jennie Garth is shocked to find out the truth when all this time she thought Kelly actually ended up with Brandon (Jason Priestley).

Binge Saturday: Beverly Hills, 90210

TVGuide.com recently tasked Garth and co-star Tori Spelling-- who have since reunited for the ABC Family series Mystery Girls--with putting their 90210 boyfriends in chronological order. While we'll give a little leeway for some of the unmemorable flings Kelly and Donna had over the years (Mark, who?), we were aghast, as was Garth, when she learned that Kelly never married Brandon (they called it off at the altar in Season 8), Kelly chose Dylan in the finale and they even had a baby (as revealed in the spin-off).
