The singer will headline two extra shows at London's O2 Arena on May 4 and 5 as part of her 'The Mrs Carter Show' global tour.
The added dates come after pre-sale for her four original dates at the London venue quickly sold out this morning (February 21).
Tickets for the shows were revealed to cost between £55 (for standing and higher tier) and £85 (for first-level seating) for her show at the O2 Arena.
The performer has also added a third date at Manchester Arena on May 9.
Beyoncé recently added extra dates in Birmingham and Manchester after demand for the shows became increasingly high.
Tickets for the star's UK tour go on general sale from 9.30am on February 23.
