Beyoncé Knowles-Carter announced on her Instagram account Wednesday she's pregnant with twins — and while all mothers want to give their children the world, Beyonce's new babies will truly want for nothing. She and her husband make up one of the most famous American power couples, with their net worths together adding up to more than $1 billion.

The popular singer, actress, fashion designer and entrepreneur has accumulated a net worth of $450 million, according to Celebrity Net Worth, making her one of the highest-paid celebrities in the U.S. Her husband, Shawn “Jay Z” Carter, a rapper, songwriter and businessman, is said to have a net worth of $700 million.

So, what’s their secret? For starters, both had their own money upon getting together romantically. Beyoncé, 35, was in a successful girl group called Destiny’s Child from 1997 to 2001 before embarking on her solo career. Since then, all of her six studio albums have debuted at No. 1 on the Billboard 200 chart — even despite the fact that two of them were released without promotion.

But what boosted her net worth tremendously were her tours. The 2016 Formation World Tour grossed over $250 million — $256,084,556, to be exact, according to Billboard. With a total of 49 sold-out shows around the globe, that averages out to about $5.2 million and 45,757 paid fans per show. Her joint tour with Jay Z, the 2014 On The Run Tour, grossed more than $100 million in ticket sales, Billboard reported.

Queen Bey is the most nominated woman and the second most-awarded woman in Grammy history, with a total of 20 wins and 62 nominations. Also bumping up her net worth were her multimillion-dollar endorsement deals with companies like H&M and Pepsi and investments in companies like Tidal, the music-streaming service she and her husband co-own with many other A-list artists. She even cofounded an activewear line, Ivy Park, last year April. Last but not least, the pop star is the founder, president and CEO of her own company, Parkwood Entertainment, which she's said she created to have control over her brand.

“When I decided to manage myself it was important that I didn’t go to some big management company,” she said in 2013 during a private screening of New York’s School of Visual Arts Theatre, according to Mashable. “I felt like I wanted to follow the footsteps of Madonna and be a powerhouse and have my own empire and show other women when you get to this point in your career you don’t have to go sign with someone else and share your money and your success — you do it yourself.”

In comparison, Jay Z has 15 studio albums — every one of which has gone platinum. In 2007, Jay Z sold his clothing wear, Rocaware, for $204 million, and just like his wife, he has huge endorsement deals with companies like Chevy, Budweiser, Armadale Vodka and Hewlett Packard. His record deal with Live Nation is worth $150 million.

In recent years, Jay Z also owned stake in the Brooklyn Nets, a professional basketball team in New York City, as well as part of their arena. He once co-owned a club in Las Vegas called 40/40 before selling it for an undisclosed amount.

Back in the music world, Jay Z signed rapper J Cole and other artists to his own record label, Roc Nation, which he founded in 2008. Most recently, he bought Tidal, a music streaming service, from Swedish parent company Aspiro for $56 million in 2015.

With all that, 5-year-old sister Blue Ivy and Beyoncé's Wednesday announcement, who wouldn’t want to be part of their family?
