January Jones is Hollywood's newest mom!
The 33-year-old X-Men actress gave birth to son Xander Dane Jones on Tuesday.
A rep for Jones says, "Mom and baby are doing great."
Jones, who has yet to reveal the father's identity, has remained faithful to her prenatal yoga classes leading up to the baby's birth.
The Emmy-nominated Mad Men actress announced her pregnancy back in April.
