Pop star Lady Gaga is set to collaborate with none-other-than pop princess Britney Spears.The 'Poker Face' singer is set to enter the studio with the 'Toxic' singer when she has finished her current 'Monster Ball' tour and she has her dad to thank for setting it up, Sun online reported.Gaga's father Joseph took the opportunity to speak to Britney at a party following the Grammy Awards last month, and told the pop beauty his daughter was a big admirer."Lady Gaga has made no secret of just how much of a Britney fan she is," a source told newspaper."She has even admitted she used to have posters of her on her wall and she was a great source of inspiration when she was a struggling songwriter.She was delighted when she found her dad chatting away to Britney at the party. He introduced them and the three of them were locked in conversation for ages," the source said."At the end of the chat, they exchanged numbers and agreed to go into the studio and work on music together as soon as Gaga finishes her tour," the source added.Lady Gaga previously revealed she has written songs for Britney and submitted her track 'Telephone' for one of her albums, but it was rejected.The eccentric pop star instead recorded a version for her recent 'The Fame Monster' album with Beyonce Knowles."I wrote it for her a long time ago, and she just didn't use it on her album. It's fine because I love the song, and it's exciting I get to perform it now," Gaga had said.The European leg of the 'Monster Ball' world tour starts on February 18, and ends in June.
