Beyonce uses body double for dangerous shoot

Beyonce and husband Jay Z are again facing rumours they are expecting their second child together.

And the 34-year-old only fueled speculation as she was spotted filming a music video in Downtown Los Angeles on Saturday, Daily Mail reported.

As she filmed, the star covered up in a baggy sweatshirt, and was seen using a body double for the video's more demanding shots.

Beyonce sported an over-sized black, zip-up sweatshirt, worn with the hood pulled up over her curly, caramel tresses.

The zip-up hoodie was also covering up a flowing, black gown that the Partition hitmaker was wearing for filming.

She stood in front of a massive, bright red backdrop on top of a building in Downtown Los Angeles for the shots.

Drones were put to use on the set, which also saw a body double for the mother-of-one, who is rumored to be expanding her family.

A woman with similarly, curly tresses to Beyonce could be seen stepping in front of the red backdrop sporting a grey zip-up sweatshirt and coordinating, skintight trousers.

The stand-in was also strapped into a large, white harness, which was then later used as she appeared to dive off the side of the building.

She also sported a brightly colored zip-up jacket and black leggings in another attempt at the daring feat.

The body double was assisted by a collection of crew members as she stood near the edge of the building before hopping off to complete the video's stunt.

Meanwhile, RadarOnline reported that from the way the Grammy winner was acting, 'it was pretty apparent' that the pregnancy rumors are true.

The source also noticed Beyonce's affinity for more form-fitting and/or revealing clothing that highlights her enviable figure.

Sporting the loose-fitting zip-up over the flowing dress 'was pretty indicative that she was covering up,' RadarOnline reported.

Beyonce was also reportedly 'complaining about being really tired and nauseous' during the video shoot. However, the star has yet to comment herself on the pregnancy rumors.
