She may have performed in front of millions at the Super Bowl, married her best friend Jay-Z and won multiple Grammys - but none of those moments compare to Beyonce giving birth to daughter Blue Ivy.
"[That was] the best day of my life," she reveals in the March issue of Vogue. "I feel like I have something that has grounded me so much more. Family has always been important. I've always had my mother and my father and my husband. But it's just...Life is so much more than...It's not defined by any of this [fame or money]."

Though baby Blue may only be a year old, Beyonce says she's never felt such a bond with anyone in her life.
"I had a very strong connection with my child," the "Single Ladies" songstress says. "I felt like when I was having contractions, I envisioned my child pushing through a very heavy door. And I imagined this tiny infant doing all the work, so I couldn't think about my own pain...We were talking. I know it sounds crazy, but I felt a communication."
Just how close are the mommy-daughter duo? "She's my road dog," the 31-year-old admits. "She's my homey, my best friend."
After taking time off to enjoy motherhood, the multi-talented entertainer is gearing up to go on one of the biggest world tours of her career - The Mrs. Carter Show.
And by the sound of Bey's connection with Blue, something tells us the li'l lady will be jetsetting with her mama.
Next up for the starlet is her HBO documentary, Life Is But a Dream, airing Feb. 16 - will you tune in?
