Worldpop reports Atomic Kitten’s Liz McClarnon has dumped her childhood sweetheart Tommy Hibbs. The warehouse manager and the pop singer parted because, as Liz admits, “We’ve been together for a long time but being in the band has taken its toll. Our schedule over the past few months has been unbelievable and it got to a point where I hardly saw Tommy at all.” In case the group flops, Liz hasn’t ruled out a reconciliation.
