Jennie Garth and Luke Perry developing sitcom

Former Beverly Hills, 90210 co-stars Luke Perry and Jennie Garth have reunited to work on a new sitcom.

The stars, who played lovers in the hit drama, were recently rumored to have started dating after they were spotted spending time together, but a representative for Garth denied the reports on Thursday (30Aug12).

Now the real reason for their regular meetings has emerged - the longtime pals are collaborating on a TV project.

A spokesperson for Garth tells website RumorFix.com, "They have been spending a lot of time together recently because the two are working on developing a TV sitcom together. It will be a multi-camera, half-hour show. Currently we have producers and writers and are meeting with networks."

The two old friends can also be seen in new TV ads for clothing firm Old Navy.
