Beyonce, who is in London this week for a six-concert stop at London's O2 Arena for her The Mrs Carter Show tour, accidentally embarrassed a British royal on Monday.

According to a report, when the Houston native turned her microphone to several members of the audience to help her sing the chorus "to the left, to the left" from her previous hit single, Irreplaceable, she placed it in front of Princess Eugenie who didn't know the words or was too embarrassed to sing along in front of the crowd.

Princess Eugenie, 23, who is the daughter of Prince Andrew and Sarah Ferguson, and sixth in line to the throne, attended Beyonce's concert with Kate Middleton's brother, James and his new girlfriend, Donna Air. British fashion designer Matthew Williamson and shoe designer Patrick Cox also went to see the multi-Grammy winner perform live.

Lainey Gossip reported that Beyonce and her husband, music mogul Jay-Z, took their daughter Blue Ivy, 1, out to dinner with Gwyneth Paltrow and her clan in London on Sunday. An eyewitness saw the actress with her husband, Coldplay front man Chris Martin, their children Apple, 8, and Moses, 6, having dinner at Zuma restaurant with the Carter family.

According to the onlooker, they met for an "early meal" that ended shortly after 8pm. There was "a lot of affection going around between" the Carters and Paltrow's clan, according to the source. Moses was seen "making jokes with (Jay-Z) at the table.".
