Beyonce, 35, and Jay Z, 47, 'tried for YEARS' to expand their family and now that she is pregnant with twins they are 'very happy'

Beyonce announced last week she was expecting twins with husband Jay Z. And on Tuesday People reported the 35-year-old superstar, who already has five-year-old daughter Blue Ivy with the 47-year-old rapper, struggled to conceive. 

'They wanted another child and after a few years of trying, it’s a great feeling,' a source told the site.

And now the Texas native is in a good place. 'She's very happy,' added the insider.

It is not known if the Crazy In Love hit maker used IVF.

Nearly four percent of babies in the United States are now born in sets of two, three or more, with the majority - about 95 percent - of these multiple births being twins, according to whattoexpect.com.
