Jodie Foster, in a sign things are getting very serious with her photographer girlfriend, Alexandra Hedison, is forsaking booze, and even attending support meetings in an effort to show her lover, a recovered alcoholic herself, how committed she is to the relationship.

The two-time Oscar winner’s “joined Alcoholics Anonymous and has embraced a 12-step program,” a friend told Star. “Now Alex has no reservations about spending their lives together … now they are both sober.”

The actress-director, 51, was persuaded by Hedison — a 44-year-old recovering alcoholic with more than a decade of sobriety under her belt — to make the moves after Foster’s casual drinking became a tangible issue between the two, Star reported.

Hedison, who dated Ellen DeGeneres from 2001 until 2004, was often prone to watching the comic imbibe with wine as she fought to resist the urges to drink, a predicament Foster has vowed not to repeat.

The Silence of the Lambs star, who was the talk of Hollywood after her revealing speech at last year’s Golden Globes “refuses to make the same mistake,” Degeneres did, says the pal.

“She’s finally found the woman of her dreams,” the source told Star, ”so giving up alcohol was nothing for her.”

“Alex wants Jodie to be sober for at least a year before they tie the knot and then it’s full-speed ahead with the nuptials. They’re crazy in love.”
