Jennie Garth, Luke Perry

West Beverly High School is having a mini-reunion, sponsored by Old Navy.

The comfort clothing retailer has recruited cast members from the original Beverly Hills, 90210 to appear in new ads — and offer winking nods to their teenage alter egos.

One of the ads features Gabrielle Carteris, who played Andrea Zuckerman, as a teacher, still harboring a crush on her now-colleague Brandon Walsh (Jason Priestley).

In another, Jennie Garth, who played perpetually lovelorn Kelly Taylor, laments having to choose among different styles of jeans — and between Priestley and Luke Perry -- who formed the Brandon-Kelly-Dylan love triangle that was a staple of the series.

Garth hinted at the reunion on Twitter last month, posting a photo of her and Perry getting cozy, with the caption "stay tuned... "

"The choice is yours," Perry deadpans in the ad, atop a motorcycle.

"So what's it gonna be?" Priestley, holding a stuffed teddy bear, asks.
