If the latest reports are to be believed, Beyoncé and Jay Z are due to welcome a second child via a surrogate.

According to In Touch magazine, the 33-year-old singer is enlisting the help of a surrogate as she and her music mogul husband add to their family.

Beyoncé gave birth to her daughter Blue Ivy, 3 years ago and the couple are now said to be eager to give her a brother or sister.

An insider reportedly told the magazine that the music power couple "are in the process of having a baby through a surrogate".

In her documentary, Life is but a Dream, Beyonce had spoken of her grief after suffering a miscarriage. It's believed her previous loss prompted the decision to have a child by a surrogate.

"They were trying for several months, but Beyoncé was having trouble. She was scared about another high-risk pregnancy, so surrogacy became the best decision for them.

"They didn't want to take any more risks, so after all the ironclad legal documents were drawn up, it took them about two months to find the perfect woman to carry their child," the insider tells the magazine. "The surrogate is still in the early stages of the pregnancy, so they have yet to announce it to the public."

The couple, whose marriage has been the focus of ongoing speculation, are also said to be hopeful that a new baby will save their marriage.

Rumours of a split intensified following the infamous elevator spat, in which Solange Knowles was caught on CCTV video attacking her brother-in-law.

"Jay's been pushing Beyoncé into having another baby to bring them closer together," the source claims. "But he's also been very protective of her and didn't want her to take any chances. He wants to make sure everything goes smoothly."

The couple have also been plagued by reports of infidelity. Rymir Satterthwaite, who was first linked to the hip hop star in 2010, filed a civil lawsuit against the 99 Problems hitmaker in December 2014 ,claiming that he is the music star's lovechild.

In 2011, allegations that the rapper had a child with Trinidad model Shenelle Scott surfaced, overshadowing wife Beyoncé's announcement that she was pregnant with the couple's first child.

"Shenelle told me that Jay-Z gave her $1m to keep her mouth shut. My understanding is that he's paying her child support," a source told Star magazine at the time.

Jay Z has never publicly addressed the love child claims.

Beyoncé and Jay Z married in secret, in 2008. The pair had been dating for six years, but kept their wedding plans firmly under wraps even denying they were married.
