The 41-year-old rapper made the most of his trip to the UK - where he watched wife Beyoncé perform at Glastonbury - by meeting Adele for lunch in London to discuss future plans.
A source told The Sun, 'It's not often he is overwhelmed by people when he meets them, but Adele was on top form as usual.
'She talked him under the table. He was chuckling all the way through their chat.
'He's keen to work with her, whether it's producing or writing together. She was a huge hit in the States and he believes they could make a massive record together.
'He told her he was going to Glastonbury and she gave him a guide of what to see. She said he must catch Paolo Nutini. She said he was the must-see act of the festival.'
