Lauren Conrad, Derek Hough split

London: Lauren Conrad, who starred in the TV series "Hills", has parted ways with her boyfriend Derek Hough.

Contactmusic.com reports Conrad has called off the relationship after just three months. "The relationship reached its peak. It was always casual. She had fun with Derek - he used to send her cute texts and sing to her - but she always kept her options open," said a source. Another source said Conrad considered Hough a rebound, after breaking up with her boyfriend of three years, Kyle Howard, in June. "This was a rebound that wasn`t going to last. Derek never thought it would either," said the source. IANS
