The 32-year-old singer has fuelled rumours she and her husband are on the rocks after she was spotted secretly viewing a $21.5m Chelsea penthouse in Manhattan last month without her spouse knowing.
"She was very quiet, as if she was looking on the sly," a source told the New York Post.
The couple - who have two-year-old daughter Blue Ivy together - currently reside in a plush mansion in Tribeca, New York, and the insider believes it's highly unlikely the 44-year-old rapper would be downsizing to the 4,045-square-foot apartment in Chelsea.
"I can say with certainty that Jay is not downsizing." The source added.
News that the 'Drunk in Love' hitmaker, who married Jay in 2008, is looking for her own place follows recent reports that the pair's marriage is "crumbling,"
"Knowing them as I do, obviously there's a little something to certain reports. When your man or your woman isn't getting it done for you, and I'm talking emotionally, not necessarily sexually...they keep things quiet."
The duo are reportedly receiving marriage therapy while on their 'On The Run' tour together but their sessions aren't proving a success as Jay allegedly prefers to spend his time on his phone.
"His phone's constantly ringing. Jay trying to make [business] deal after deal," the source added.
Could all these rumours finally be true? Is Beyonce soon to be a single lady?
