Reunited — and it feels so good!

That's what former "Beverly Hills, 90210" (search) lovebirds Jennie Garth (search) and Luke Perry (search) seem to be saying as they get together again, this time for an upcoming episode of The WB's "What I Like About You." (search)

Garth and Perry, who played "90210" sweethearts Kelly Taylor and Dylan McKay on the '90s Fox teen drama, look like they haven't lost a step — or that special something they had for each other back in the day.

In the episode, titled "Dangerous Liaisons," Perry plays Todd, a plumber who's hired to work in Val's (Garth) bakery.

There's a problem, though: Seems that Todd and Val had a one-night-stand back in high school — and now Todd wants to reignite the flame!

The episode, airing Feb. 25, kicks off a special "Flashback Friday" on The WB, where all of the network's shows will have a flashback component.
