Beyonce has been attending spinning classes with husband Jay Z to keep fit while she's pregnant.

The 35-year-old R&B superstar is expecting twins with the 'Encore' rapper, but that isn't stopping the brunette beauty from getting exercise as the couple are regulars at SoulCycle, where they do the intense cycling workout.

And on Wednesday (08.03.17), she even took her former Destiny's Child band mate Kelly Rowland along for a class in West Hollywood.

A source told Us Weekly magazine: ''She's been taking a class almost every day.''

Hollywood's power couple will reportedly learn the genders of their expected twins this month.

The 'Lemonade' hitmaker - who revealed her pregnancy via Instagram - was apparently overheard telling guests at a pre-Oscars bash last month that she and her rap star spouse will know what they are having in the next couple of weeks.

A source previously revealed: ''She was telling people they'll know the genders of the babies in two weeks.''

Despite the excitement and speculation surrounding Beyonce's pregnancy, the chart-topping star has so far declined to reveal when she is due to give birth.

However, the celebrity duo are planning to buy a 123-room mansion to accommodate their growing family.

The couple - who have five-year-old daughter Blue Ivy together - secretly viewed an £85 million Hollywood abode belonging to heiress Petra Stunt and her businessman husband James Stunt earlier in February.

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.''

But Beyonce and her 47-year-old husband are said to be reluctant to pay the asking price for the house, despite their vast wealth.

The source explained: ''They said they want to get a good deal though, so they were keen on getting the price down.''
