Enrique Iglesias has sparked rumours he has proposed to long-term girlfriend Anna Kournikova, after the tennis ace was spotted wearing a $6 million (£3 million) engagement ring.

The singer has previously refused to confirm the couple is engaged, but the sportswoman was photographed in London wearing a diamond on her left hand on Tuesday (04Dec07) in London.

Earlier in the evening, the pair had enjoyed a romantic but unique meal in the capital - the chef at Japanese eaterie Sapporo Teppanyaki lobbed food at the pair so they could catch it in their mouths.

Iglesias has been dating Kournikova since 2002, after she starred as his girlfriend in the video for hit Escape. (JC/WNTEX&WNTSU/CG)
