Beyoncé has admitted she is Jay Z's ''biggest fan''.

The 33-year-old 'Drunk In Love' hitmaker made the admission during the final night of the couple's 'On The Run' tour.

She said to her husband in front of a packed stadium of 81,000 people in Paris: ''I'm your biggest fan''.

He responded saying: ''It's been an honour and a pleasure to share the stage with you.

''I couldn't dream for anything else [than] to be in this stadium with the woman I love, who I believe is the greatest entertainer of our time. I love her. She's my wife.''

Meanwhile, the 44-year-old rapper was happy to share with the crowd why Paris was so special to them.

He explained: ''We love Paris. It's special to us because we got engaged here and this is where baby Blue was conceived.''

The two shows at the Stade de France were filmed as part of an upcoming HBO special.

Meanwhile, Parisian fans were also treated to a surprise appearance from Nicki Minaj.

The 31-year-old singer joined Beyoncé on stage to perform their remix of 'Flawless' for the crowd.

Alongside a picture she posted on Instagram of the pair on stage, Nicki wrote: ''Tonight was their last show which made it even more special.

''Honored to have experienced this with two ppl who've influenced me more than they'll ever know. Thank you BEY&JAY :)'' (sic).
