Here comes another porn parody.

from www.tmz.com – Meredith Baxter — Michael J. Fox’s mama “Elyse Keaton” on “Family Ties” — just came out as a “later in life” lesbian.

Baxter, who’s been married to men three times and has five children, revealed on “Today” she has been in a relationship with a woman for the past four years — and the couple lives an out life together in L.A.

The revelation comes right as National Enquirer released a story saying Baxter went on a cruise with 1,200 other lesbians.
