Los Angeles, Dec 18 : Rapper Jay Z was guarding a toilet at a vegan restaurant here while his wife, pop star Beyonce, used the facility in peace.

The 44-year-old stopped anyone from entering the washroom, but his gesture did not go down well with the other diners who had to queue until Beyonce was done.

"Halfway through their meal, Jay got up and asked a waitress to check if anyone was currently in the bathroom," dailystar. co. uk quoted a source as saying.

"Once they had established the loos were empty, Beyonce scurried inside while he stood guard over the door. When a couple of customers tried to go in, he politely asked them if they'd mind waiting until his wife was done. Some customers were a bit miffed, but Beyonce was also embarrassed when she came out," the source added.

The drastic actions may have seem irrational for some, but Beyonce likes to have privacy when she uses public toilets as several times fans constantly keep approaching her.

"She gets scared of getting accosted by someone who recognises her in public bathrooms. If she has a female friend with her, she always gets them to accompany her. But this time it was just her and her husband," the source said.

Afterwards, the couple reportedly signed autographs and posed for photographs for fans who waited patiently.(IANS)
