Groove back, ‘Stella’ author files for divorce

Author Terry McMillan has filed for divorce from the man who inspired the 1996 novel “How Stella Got Her Groove Back,� which chronicled the romantic adventures of a 40-ish woman who falls for a guy half her age.

In papers filed in Contra Costa County Superior Court, McMillan, 53, says she decided to end her 6 1/2 -year marriage to Jonathan Plummer, 30, after learning he is gay.

McMillan filed for divorce in January, but news of the split didn’t surface until this week, when it was first reported in a San Francisco Chronicle gossip column. Earlier this month, a judge ordered McMillan to pay Plummer $2,000 a month in spousal support and $25,000 in attorney’s fees until the case comes back to court in October.
