As Ashanti can attest, not every doe-eyed, sultry soprano with a No. 1 debut album can be a boy magnet. "I've been getting no guy action," insists the 21-year-old R&B singer. "If I go to a club, the Murder Inc. [her label] guys surround me, so no guy in his right mind would talk to me. I'm the little sister." Perhaps, but as the first artist since the Beatles to have three singles in Billboard's Top 10 at once, Ashanti Douglas has also become an industry player. "I had to line my name up with the [Billboard] numbers like 10 times," she says. "I was in shock." Not so her mom, Tina, 47, and dad, Thomas, 48, both computer specialists. "She looks innocent," says Tina, "but if there's something she wants, she'll get it." Still, Ashanti, who lives with her folks in Glen Cove, N.Y., is staying grounded. When pals suggested she buy a $120,000 Mercedes, she replied, "It only has two seats. I couldn't bring my family anywhere."
