Whitney Port is following her The Hills co-star Lauren Conrad to the altar - the reality Tv regular-turned-designer has announced her engagement.

The 28 year old is set to wed Tim Rosenman, who served as an associate producer on her The Hills spin-off The City, after a year of dating, her representative has confirmed to People.com.

Port's happy news emerges just weeks after Conrad announced she is to exchange vows with law student William Tell, while another The Hills alum, Holly Montag, recently revealed she is engaged as well.

However, The Hills bad boy Jason Wahler is already one step ahead of the girls - he married model Ashley Slack a day before ex-girlfriend Conrad revealed her plans to wed.
