Kate Walsh apparently wants everyone to know that she's dating a younger guy -- she just doesn't want to talk about it. The "Private Practice" star, who remains embroiled in an acrimonious divorce from studio exec Alex Young, made a PDA-tinged debut at the Emmy Awards with an actor named Neil Andrea. According to the New York Daily News, the two were spied swapping spit during an afterparty to the unromantic strains of "I Will Survive." People magazine adds that Walsh, 41, introduced her dark-haired date, 35, as "my boyfriend" to Chris O'Donnell. Still, she played it coy when the mag asked about the nature of their relationship. "I'm not going to talk about that!" deflected the actress, who also appeared with Andrea on Monday night at a "Private Practice"-related charity event. "I know you have to ask, but it's super top-secret! It's in the vault!" Let's just hope Kate takes things a little more slowly this time around. You'll recall that she tied the knot with Young in September 2007 after only three months of togetherness. They split a little more than year later, although the financial wrangling drags on.
