Anne Heche is letting her classical training show.
The actress has given birth to a son, her second, who joins older brother Homer with a name borrowed from ancient Greece. Atlas Heche Tupper was born over the weekend and weighed 6 lbs., 12 oz., the actress's rep tells PEOPLE.
"They are ecstatic," the rep says of the new parents.
Heche and the boy's father, actor James Tupper, met on the set of ABC's "Men in Trees" and began dating in 2007. They announced they were expecting in December last year.
Heche's other son, Homer, 7, is from her marriage to Coley Laffoon, which officially ended Wednesday.
Heche and Tupper recently picked up a few baby boy items at the Boom Boom Room's Children's Gifting Wonderland in Los Angeles, including a pair of Robeez Guitar leather booties and a blue MiGi baby blanket.
