Jay-Z has decided to put his career on hold
a bit for daughter Blue Ivy Carter
, but for new mom Beyoncé
, the show must go on.
"I'm back to work," the pop diva, 30, says in a video
showing the process leading up to her return to the stage Memorial Day weekend at Revel resort in Atlantic City, N.J. "I'm back to business."
But the brief hiatus from her career that she's taken since giving birth does make her feel mixed emotions about returning to the stage.
"It is exciting," says PEOPLE's Most Beautiful Woman
. [But] I feel a little nervous. I enjoy being a mother. [Performing] is like going back to my old job. It's a little strange."
The "Single Ladies (Put a Ring On It)" singer also understands, though, how crucial it is to have a life outside of family.
"It's important that … you have your own passion," she says, adding during a session with her tour crew, "What I'm trying to say at this show is 'Yeah, I just had a baby, but it just made me more grounded and more like you.' "
