Anne Heche and James Tupper

It's a boy for Anne Heche and boyfriend James Tupper.

Heche gave birth to her second son over the weekend, according to People. The baby, the couple's first together, tipped the scales at 6 lbs. 12 oz. "They are ecstatic," their rep said.

The newborn is named Atlas Heche Tupper. The name is in keeping with Heche's affinity for Greek mythology — she has a 7-year-old son named Homer from her marriage to Coley Laffoon, which officially ended in a settlement Wednesday.

Heche and Tupper met on the set of the ABC drama Men in Trees, and began dating in 2007. They announced they were expecting in December of last year.
