The original song, "What I Like About You," was recorded and released by The Romantics on their debut album in the late 1970s and remains one of the band's biggest hits. Lillix's remake of The Band's 1978 hit "Who Do You Love" is the music for The WB's current on-air promotional campaign.

"The WB ratings for women 18-34 has always been a strong demographic for our network and a group like Lillix fits right in," said Jordan Levin, President, Entertainment of The WB. "We knew the minute we heard their music last spring and signed them for the on-air campaign that we would be doing something else with this group again soon."

Lillix includes vocalist-guitarist Tasha Ray Evin (17), vocalist-keyboardist Lacey Lee Evin (18), and singer-bassist Louise Burns (16), all from Cranbrook, British Columbia. The band's career took off when Burns' father sent a demo of the all-girl teen group to an entertainment lawyer. Madonna's record label company, Maverick, quickly signed the girls upon their first meeting.

WHAT I LIKE ABOUT YOU also stars Simon Rex and Wesley Jonathan. Wil Calhoun ("Friends") and Dan Schneider ("The Amanda Show") serve as executive producers, along with Mike Tollin, Brian Robbins, and Joe Davola ("Smallville") for Tollin/Robbins Productions in association with Warner Bros. Television.
