January Jones has given birth to a baby boy.

The X-Men: First Class actress welcomed her first child on Tuesday and has named him Xander Danes Jones.

The 33-year-old beauty has chosen not to reveal the father of the baby.

Super 8, the family-friendly SciFi adventure produced by Steven Spielberg and directed by J.J. Abrams, had a super opening at the box office this weekend.

With stars Kyle Chandler and Elle Fanning, the flick took in an estimated $38 million in tickets.

Second place went to The Hangover Part II which took in another $32.4 million.

The surprise hit of the summer, Bridesmaids, finished fifth with $12 million, but more importantly, it has now grossed $107 million.  Not bad for a film that was produced for just over $32 million.
