Tennis: Anna Kournikova set to marry?

Anna Kournikova is reportedly engaged to her boyfriend Sergi Federov.

The 19-year-old was spotted wearing a spectacular and expensive-looking diamond ring.

She said it was a present from the ice hockey player.

Although the rumours have not been confirmed, neither of the pair's families have come forward to deny them.

In the past Anna's been romantically linked with Brazilian footballer Ronaldo and another ice hockey player, Pavel Bure.

The tennis star is currently ranked number eight in the world, and earned £10m last year, mostly from modelling and advertising.
