Jay Z has finally responded to his wife Beyoncé's new album 'Lemonade', in which she hinted he's been unfaithful.

Featuring on the song, he raps: "You know you made it when the fact/ Your marriage made it is worth millions/ Lemonade is a popular drink, and it still is/ Survival of the littest. (sic)"

The couple - who got married in 2008 and have four-year-old daughter Blue Ivy together - sent the internet into overdrive at the end of April when the 34-year-old beauty released her hour-long visual album in which she hinted her spouse had been cheating on her with a woman named Becky.

In one track, 'Sorry’ Beyoncé sang: "Looking at my watch he should have been home/ I regret the day I put that ring on/ He always got them f***ing excuses/ He only want me when I'm not on there / He better call Becky with the good hair."

By the end of the album, the pair - who have been rocked with affair allegations for years - have seemingly patched up their differences and prepared to give their marriage another go.

However, although many fans were quick to lash out at the rapper for his alleged behaviour, some people believe the whole album may just be a publicity stunt to rake in cash.

Though speculation is still rife, almost four weeks on from the release, it's thought the couple are planning to address the claims on a forthcoming secret album.

A source said recently: "Jay and Beyoncé were never going to do an interview to address all the questions that came up after 'Lemonade.' It's more their style to respond through music."
