The supercouple enjoyed a date night at New York's Richard Rodgers Theatre, where they checked out the hip-hop musical about U.S. founding father Alexander Hamilton, but kept their attendance a secret until just before the curtain went up.

A representative tells Beyonce and Jay purchased tickets for the production and show bosses weren't aware they were coming until "very late".

The couple also requested to go backstage following the performance to meet the cast, including leading man Javier Munoz, the alternate for creator and star Lin-Manuel Miranda, who has missed the past few shows due to illness.

Beyonce and Jay, who happily posed for pictures with the rest of the cast, haven't been the only stars to stop by the record-breaking musical - Oprah Winfrey, Jennifer Aniston, Katy Perry, Selena Gomez, Ben Stiller, Matthew MCConaughey, Cate Blanchett and Kerry Washington have been among the celebrities who have lined up to see the musical and meet the cast backstage since it opened to rave reviews in July (15).

U.S. President Barack Obama is also slated to see the production for a second time on 2 November (15), as part of a political fundraiser.

Meanwhile, Beyonce and Jay dominated a stage of their own the night before with their Tidal X: 1020 charity gig in Brooklyn, New York on Tuesday (21Oct15). As part of a celebration to mark the success of the his Tidal music streaming service, which recently signed up its one millionth subscriber, the rapper recruited a star-studded line-up to perform at the Barclays Center.

In addition to Beyonce and Jay, Nicki Minaj, Rick Ross, Lil Wayne, Meek Mill, Usher, Nick Jonas and Thomas Rhett were among the artists who performed in front of a sold out crowd.
