Deborah Claire Wesoff-Kowalski (born March 10, 1966), known professionally as Debbie Deb, is an American singer and songwriter best known for her 1980s freestyle dance singles "Lookout Weekend" and "When I Hear Music".

Released on the Jam Packed record label in 1984, the song has since become a staple in clubs and on dance and urban radio stations and mixshows.

As a result, she made little, if any, money from her hit singles, and was so hurt by the experience that she stopped singing for years, relying on her work as a hairdresser to make ends meet.

Gwen Stefani and Jonathan Davis of Korn have cited Deb as an influence, and in the summer of 2006, Janet Jackson featured a cover version of "Lookout Weekend" on her website.
