Beyonce Knowles has an `X-Factor` fan

London: Beyonce Knowles has millions of fans around the world and one of them is `X-Factor` winner Joe McElderry who was so determined not to miss a minute of her concert that he almost wet himself.

The 19-year-old singer who recently came out as gay, was so excited to see his idol in the flesh that he refused to go to the toilet and spent almost the entire show desperate to relieve himself, reported Contactmusic.

"I went to see her. And I was desperate for the toilet and I would not leave in case I missed a tiny bit. My cousin was like, `Just go to the toilet,` I just kept saying, `No! I`m not going!,"said McElderry.

The singer who shot to fame after winning the UK talent show last year, said that he would love to work with the `Single Ladies` hitmaker in the future.

"Beyonce is the top one. She`s amazing. She acts the songs. And she has got the right balance between it all and she just connects with the cameras. She outdoes her dancers. Her dancers are flagging and she is still going! That takes a lot, he said."

Besides Beyonce, McElderry has a huge list of people whom he wants to collaborate with, including his former `X Factor` mentor Cheryl Cole.

"I think it might be interesting if I could a duet with someone who wasn`t the same kind of style as me. Someone like Ne-Yo. Create a quirky sound! Or Rihanna," the singer said.

"Cheryl, she is an amazing performer and singer and she`s fantastic so I`d be honoured to work with her! But it depends, I suppose. You never know what`s going to happen," he
