Happy 30th Birthday Beyonce!

It's been quite the past year, as Beyonce Knowles dropped her fourth studio album "4" while also having just recently announced that she's expecting her first child with husband Jay-Z.

And the superstar singer just so happens to be ringing in her 30th birthday today (September 4) while currently spending time out of public view with her rapper hubby in Venice, Italy.

Keeping true to her word, Miss Knowles - who revealed the baby news at the MTV VMAs late last month - previously said on 'Piers Morgan Tonight,' "I always said I would have a baby at 30."

As for the pregnancy details, an insider told Radar Online, “Beyonce is about three months along and is due in February. She and Jay are absolutely over-joyed...her whole family is really excited.”

With a big happy birthday in order, the source added of the couple, “Of course having a little boy for Julez [sister Solange's son] to play with would be ideal, so they have their fingers crossed."
