Once considered the rock solid couple of showbiz, Bey and Jey’s marriage was shook when wife Beyonce alluded to hubby Jay-Z’s infidelity in her most recent chart-topping visual album, Lemonade. Award-winning rapper Jay-Z then responded with 4:44 - widely regarded as his apology album to his wife of nine years and confirming the rumours surrounding the two.

Following that, Jay-Z confirmed the cheating scandal in a candid interview with the New York Times and admitted that an emotional shutdown caused him to stray.

Now a source has revealed global superstar Beyonce only stayed with the father of her three children - real name Shawn Carter - because of their first born, five-year-old, Blue Ivy.

The pair welcomed Blue in January 2012 and, after getting over Jay-Z’s infidelity, have since welcomed twins, Rumi and Sir Carter now five months old.

Referring to the reason why 36-year-old Beyonce decided to give their relationship a second try, People Magazine reported that it took a long time for her to trust her husband again.

The source said: "It was very rough for them to stay married. It took Beyonce a long time to trust again. She was struggling to move on and forgive.

"But keeping her family together was very important."

The insider went on to reveal the primary reason and said: "If it wasn't for Blue Ivy, they might not be together.

"It took them years to get to the point where they are now."

Adding: "They are both very proud that they overcame huge marital issues and happy they were able to move on as a family."

Speaking to the NYT about how he felt when he heard the Queen of Pop reference the hurt he had caused in her album, Lemonade, Jay-Z said it was "very, very uncomfortable" and it felt like being "in the middle of a hurricane".

He said: "The best place is right in the middle of the pain. And that's where we were sitting. And it was uncomfortable. And we had a lot of conversations.

"[I was] really proud of the music she made, and she was really proud of the art I released."
