Beyonce's Explicit Lyric Boosts Seafood Chain

An explicit lyric in Beyonce's new song, about going to Red Lobster after sex, has boosted the US seafood restaurant's fortunes.

The Orlando-based chain says it is certain the artist's new single, Formation, is responsible for at least part of its 33% sales jump on Sunday from a year ago.

"When he **** me good I take his a** to Red Lobster," the singer - dubbed Queen Bey - raps in the song, which was released on Saturday morning.

The chain was a trending topic on Twitter over the weekend for the first time ever.

Red Lobster chief executive Kim Lopdrup said in a statement: "It's clear that Beyonce has helped create some Red Lobster fans, and we are very grateful to her for that."

Beyonce performed a version of the new song , her first since 2014, at Sunday's Super Bowl half-time show.

Formation, and its video, have attracted headlines for their implicit commentary on police brutality and Hurricane Katrina.

Red Lobster, known for its cheddar biscuits, has more than 700 locations in the US and Canada.

The chain was sold by Darden Restaurants in July 2014 after an ongoing decline in sales.

Now privately held by investment firm Golden Gate Capital, it says it has posted sales gains every quarter since the separation.
