TEASE: Beyoncé leaves fans krapping their koppe over the gender of her twins in video.

Beyonce celebrated her pregnancy with a trip to Bora Bora.

The Crazy In Love hitmaker and her husband Jay Z jetted off to the island in the French Polynesia in what will probably be their last holiday before they welcome their twins, E! News reports.

The 35-year-old singer – who has five-year-old Blue Ivy with jer husband – was meant to be headlining the Coachella Valley Music and Arts Festival this weekend but pulled out after she found out she was expecting.

Meanwhile, Beyonce and Jay Z are reportedly planning to buy a 123-room mansion to accommodate their growing family.

A source said: "Beyonce and Jay Z are actively hunting for a house, something they can settle in for the next decade or so, and Petra's place seems to be very appealing to them.

"They were shown around two weeks ago and are thinking about whether it works for them. They know with their expanding brood it's time to get serious about laying some roots, and having a statement pad in Hollywood is at the top of their list. They loved the space and the size, they just need to work out if it's the right fit for the future. They said they want to get a good deal though, so they were keen on getting the price down."

And Beyonce's daughter can't wait to be a big sister.

A source shared: "Blue is so excited to be a big sister! They are ecstatic. They have been trying for a long time and now to be blessed with twins they are so over the moon. It's even better than they wished for."

Beyonce announced her pregnancy with a post on Instagram.

Displaying her baby bump, the Formation hitmaker wrote: "We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters (sic)"
