St. Moritz, Switzerland - Boris Becker legally married dutch model Lilly Kerssenberg in Switzerland on Friday, as the couple completed the first stage of their wedding ceremony in the Swiss mountain resort of St. Moritz.

A close group of friends and family witnessed the ceremony at the civil registry office, as the sun shone on the 41-year old tennis legend and his 32-year-old bride in her bright white dress.

The couple are to exchange vows in an alpine chapel later on Friday.

Boris Becker and Kressenberg rekindled their relationship after he separated from his former fiancee Alessandra Meyer-Woelden, the 26-year-old daughter of his late manager, just seven months ago.

Becker sold the broadcasting rights for his second wedding to German RTL television network. (dpa)
