The veteran actress, who portrayed supermum Elyse Keaton on the hit 1980s show, confirmed rumours she is gay in this week's (begs30Nov09) People magazine.
The 62 year old revealed she has been living as a lesbian for the past seven years and has found love with building contractor Nancy Locke, who she moved in with in 2007.
Gross, who found out Baxter is gay in 2005, is fully supportive of her decision to share her sexual orientation with fans and is delighted his pal has found happiness.
He tells People.com, "She's one of my favourite people in the world, and I'm just thrilled that it's no longer a secret, and that's about the size of it. I'm just thrilled this has happened because now my wife and I don't have to hide this from everybody we know. Occasionally people will say to us, 'Hey, Michael, you still see your co-star? How's she doing? Is there a man in her life?'
"Meredith's children are very accepting of this (her sexual orientation) and I myself have met Meredith's partner on numerous occasions. I've travelled with them. She's just a first-rate individual - and I like her a lot. My wife does as well."
