Becker and Lilian started dating in 2019. They tied the knot in September 2024 in a small village in Italy called Portofino. The German spoke about his marriage in an interview with 'Hello Magazine' last year.

"It was authentic, it was real and it was a magical weekend I will never forget. We live in Italy and we went to Portofino a few times last summer. We could have chosen Venice, Rome, or Lake Como, but our strongest attachment was to Portofino."

Boris Becker has gotten married three times so far. He first tied the knot with Barbara Feltus, then had a brief association with Lilly Kerssenberg, and finally settled down with Lilian Monteiro.

The German spoke about his connection with Monteiro and felt that she was an attractive woman from the start.

“She is obviously a very attractive woman, but I felt that from the first day we had lunch together alone. We also had this instant intellectual connection. Even though she’s 20 years younger, I feel like she has an old soul and I like to think my soul is a bit younger, so we met in the middle," Boris Becker said via Express.

The former World No. 1 now has five children. His first son, Noah Gabriel, was born in 1994 when he was married to Barbara. His second son, Elias Balthasar, was born in 1999.

Becker then acknowledged his daughter, Anna, in 2001 after his divorce and welcomed his fourth child, Amadeus Benedict Edley Luis (son), in 2010. The Germans' latest addition to the family is Zoe with Lilian Monteiro.
