Tennis' most glamorous couple, Andre Agassi and Steffi Graf, are set to marry, the BBC has learnt.

The news, which is likely to send shockwaves through the world of tennis, ends months of speculation surrounding their relationship.

Last month, Steffi Graf attended Agassi's victory at the Australian open, amid rumours they had already married.

After his victory in Melbourne Agassi denied the speculation, though neither player has so far commented on the latest reports.

The couple first got together after they both won the French Open last year.

Graf has since retired, but is never far from Agassi's side at tournaments.

With her support Agassi has moved from 141st to number one and now the talk is of marriage in the summer.

BBC tennis correspondent Iain Carter said: "A leading figure in world tennis has been speaking to a close association of the Graf family and has told me the plans are for her and Andre Agassi to get married.

"The wedding will take place on Steffi's birthday which is June 14.

"It is ideally placed as far as British audiences are concerned because that's very close to Wimbledon just after the French Open."

Graf made her final appearance losing in the Wimbledon final last year, but both she and Agassi are sure to receive another ovation at this year's tournament - both on and off the court.
