Another Hollywood marriage is in trouble. In Touch can exclusively reveal that on Oct. 8, a visibly upset Gwen Stefani, 43, left a couples therapy session in LA with husband Gavin Rossdale, 46. “Over the past two years they’ve spent less and less time together,” a source close to the couple tells the new issue of In Touch, on newsstands now. Although the pair have denied they’re splitting, the source reveals, “They used to be affectionate with each other and laugh a lot. That never happens anymore.” The couple’s troubles stem from the Bush front man’s busy tour schedule, which prevents Gavin from spending time with his wife and their sons, Kingston, 6, and Zuma, 4. “There were months where he wouldn’t even be at the house,” says the source.
