Is the world's power couple calling it quits? A new rumor claims Beyoncé is ready to give up on her 5 year marriage to rapper Jay Z, according to Star magazine via Celebrity Dirty Laundry.

Reportedly a source told the tabloid that the "Diva" singer feels Jay Z has been ignoring her and their 19-month-old daughter Blue Ivy and is ready to take a break from the marriage. The source said Beyoncé has been considering a trial separation to see if the two would be better off apart.

According to Star's story the "Magna Carta" went to visit Queen Bey in Australia. The two took a 3-day vacation together but instead of it being a nice bonding time the source claims it was the rapper's last ditch effort to get back in Beyoncé's good graces.

"Jay Z's early November trip to Australia was not just a family getaway, it was a last-ditch effort to keep his marriage afloat," the source said. "Jay Z's decision to tour Europe at the same time as Beyoncé is touring Australia has caused serious damage to their relationship - damage that may ultimately prove to be irreparable."

This source continues by saying that Beyoncé had no problem with her husband touring with Justin Timberlake over the summer but wanted him to come on her Australia/New Zealand tour so they could spend time together as a family. Instead the rapper has allegedly been photographed partying and clubbing a lot.

"Not only did he plan the tour without consulting her at all, he didn't even try to coordinate dates with her tour. She told him he was selfish," the source said. "Beyoncé has been feeling like a single mother lately - and has been letting her husband know he's on shaky ground, and she's using the time they spend apart as a trial separation."

The couple is usually very private about their personal lives and probably won't address these rumors but we'll let you decide if you believe this rumor.
