It's baby number two for Christian Bale and wife Sibi Blazic. Reports indicate that the couple welcomed their second child recently, a son.

But with pictures surfacing of toned Blazic out and about, some may speculate as to when the Bale family actually said hello to their newest edition.

People Magazine reports that Bale and his wife recently had a son. The couple, who tend to remain private about their personal lives, have yet to release the baby boy's name or details about the child.

According to the Daily Mail, Blazic was spotted on Sunday running errands. The new mom was seen wearing workout gear, which displayed her trim figure.

The Daily Mail speculates that Blazic may have, in fact, given birth some time ago.

The pair also have a nine-year-old daughter. 

Bale, typically reserved when it comes to sharing information about his family life, gushed about his family to Parade in 2008.

"My wife and daughter come with me on location," Bale told Parade that year. "It's the most ideal mix. These wonderful distractions actually make me better at what I do."

Regarding fatherhood, Bale seems to enjoy the role. In an interview with Esquire, the "Dark Knight Rises" star opened up about how being a daddy has changed him for the better.

"The last few years of my life have been spent just watching animation-for my daughter-and getting a kick out of that," admitted the actor. "I love anything that she likes. If she's getting a kick out of it, I love it."

In 2009, Bale admitted to People Magazine that having a family had changed him. "It' all about my girls, my wife and my daughter. I carry a picture of them with me all the time.

The "American Hustle" actor even admitted to getting emotional when watching movie with his daughter.

"I find myself tearing up at the most ridiculous things now, "sitting next to my daughter while she's watching a movie. Me and my wife look across at each other like, 'Oh my God! Are we really doing this? Yes we are!'"
