Liv'll just sort of say to me after, 'Mom, you should have worn a different color underwear'."īuell airs even more laundry in her memoir, "Rebel Heart," a funny and scandalous Alice in Wonderland story about a former Catholic-school girl who comes to New York as a teenager to model and stumbles into a strange world where everybody's snorting coke off the looking glass. "I don't do it all the time, but sometimes the Iggy does enter my blood and I do get outrageous onstage. "I think she would prefer it if I didn't take my pants off when I performed," she says. Later, when you ask if her daughter is ever embarrassed by the Bebe Show, Buell reflects for a moment. She belts out some bright punk tunes, dances and struts like Tyler and Jagger, strokes the microphone stand suggestively and shakes her hair (among other things). Buell is playful, magnetic and clearly exhilarated at being the rock star for a change. On a July evening Buell, 48, and her band take the stage at CBGB's in New York. "Let me beat you up! Then make up your mind." Fair enough. "Come to one of my shows!" she'll tell you. Before you judge Bebe Buell-before you dismiss her as merely the mother of Liv Tyler, or the ex-girlfriend of Steven Tyler, or the ex-girlfriend of Jimmy Page, Mick Jagger, Iggy Pop, Rod Stewart, Elvis Costello and Todd Rundgren-you really should see her rock.
