Even if it doesn't work out, Union won't stay single long—she never does.
Russian beauty Anna Kournikova may not have accomplished much during her brief career as a professional tennis player, but she certainly managed to catch the eye of a few athletes during that time.
Kournikova was linked to NHL stars Pavel Bure and Sergei Federov and Australian tennis player Mark Philippoussis before hooking up with singer Enrique Iglesias in 2002. Kournikova and Iglesias met on the set of one of his goofy music videos in 2002 and have been attached at the hip ever since.
Perhaps she'll go back to familiar dating territory if things don't work out with Iglesias, but with a decade of lovey dovey PDA under their belt, it's hard to imagine these two…not together. But Simpson met former NFL tight end Eric Johnson in 2010, and the pair welcomed their first child in 2012 and are currently engaged.
Prior to that Simpson had a high-profile romance with Cowboys quarterback Tony Romo and skateboarder/Jackass Bam Margera. Count on Simpson and Johnson keeping it together long enough to walk down the aisle—probably with reality TV cameras trailing them.
But it's very hard to imagine these two together long term, and I can't see Simpson wanting to keep watch on the wandering eye that many athletes seem to possess.
