Top 20 Strangest Celebrity Couples

16. David Cross and Amber Tamblyn

These two are an oddly mixed pair, but they have a great relationship. It is rumored to have started when they were seated next to each other on a plane, and they realized throughout the flight how compatible they were. The 19-year age gap does not seem to hurt their relationship at all. They became engaged in 2011 after dating for two years. Then they tied the knot in 2012.
