AGE: 34. OCCUPATION: Singer-songwriter. DOMESTIC PARTNER: Film director Julie Cypher (Teresa’s Tattoo), ex-wife of Lou Diamond Phillips. CAME OUT: To hundreds of guests at January 1993’s Triangle Ball in D.C., the gay and lesbian inaugural bash. CAREER IMPACT: Hasn’t crimped her ascendancy as a VH1 darling one bit. LYRICAL APPROACH: With titles like ”Yes I Am,” her songs play swell as lesbian anthems — but with no gender-specific pronouns, they’re also straight friendly. WORST TABLOID INDIGNITY: Stories suggesting a romance between her and hunky country star Billy Ray Cyrus.
