In Hollywood, pregnancies aren’t too shocking – neither are breakups quite frankly. But what is surprising is celebrity marriages. The Summer of 2010 can easily be dubbed as the “Summer of Commitment” in Hollywood, with upwards of nearly 25 celeb couples tying the knot.

While it appears there is an influx of unions in Hollywood, there’s always a flip side to that fairy tale story. In Hollywood, where there’s a wedding, there’s a divorce lurking not too far behind.

Still, there’s a fair share of celeb’s who are keeping wedded bliss at bay – opting to be fully committed to one another – even starting families together – without tying the knot. Here’s the Top 5 Happily UnMarried Hollywood Couples.
