Jay Z is allegedly ''pulling out all the stops'' to save his and Beyoncé's marriage.

The 44-year-old rapper is reportedly determined to prove to the 32-year-old singer, whom he married in 2008, how much he cares about her following rumours their romance is allegedly on the rocks.

A source told E! News: ''There has been talk of divorce and it's been really tense at times on the tour. Beyoncé has been leaning on her mom and sister a lot since they are so close.

Jay wants everything to work out and is trying to convince Beyoncé how much he does not want a divorce. It's flowers, constant texts and telling her he loves her. He is pulling out all the stops.''

The couple, who wrapped up their 'On the Run' tour on August 6 in San Francisco, will travel to Paris in September for two shows and are keen to keep their relationship as ''professional as possible.''

The source explained: ''While they're still on tour, it's all business. They're professionals and they're trying to keep everything as professional as possible.''

The pair, who have two-year-old daughter Blue Ivy together, are reportedly staying at their good friend Gwyneth Paltrow's Los Angeles mansion over the summer as the Brentwood property offers them privacy.
