Lifestyle: Beyonce and Jay Z are officially a billion dollar couple

Her Formation World Tour alone grossed a quarter of a billion dollars.

Beyonce and Jay Z, already two of the biggest names in music, are officially a billion-dollar couple.

According to Forbes list of America's Richest Self-Made Women, released on Wednesday, 35-year-old Beyonce Knowles is worth $350 (£270) million. Her Formation World Tour alone grossed a quarter of a billion dollars.

Meanwhile, a recent Forbes ranking of The Richest in Hop Hop of 2017 revealed that Jay Z's fortune has jumped 30% in the past year to $810 (£625) million, putting the couple's combined net worth at $1.16 billion (£890 million).

This is partly due to a $200 (£154) million investment from Sprint into his music-streaming service, Tidal, which is now reportedly worth $600 (£463) million — more than 10 times what he paid for the company ($56 (£43) million) two years ago.

Together, the Knowles-Carters hold "significant equity" in Tidal.

However, according to Forbes, most of the Jay Z's wealth comes form his entertainment company, Roc Nation, and his Armand de Brignac champagne brand, both of which continue to grow.

Just last week, Jay Z also signed a new 10-year, $200 (£154) million deal with Live Nation.

The news comes as the couple are preparing to welcome twins to their family this summer.

They already have a 5-year-old daughter, Blue Ivy.
