Boris Becker and his wife Lilian de Carvalho Monteiro have welcomed a baby girl into the world.

The 58-year-old former professional tennis player took to Instagram on Saturday (22.11.25) to announce that Zoe Vittoria Becker was born on Friday (21.11.25) - a day before Boris' 58th birthday.

Captioning a sweet photo of the couple holding the tot's hand, he wrote: "Welcome to the world … Zoe Vittoria Becker 21.11.2025."

Zoe is the six-time Grand Slams winner's fifth child.

Boris has sons Noah, 31, and Elias, 26, with his first wife, designer Barbara Feltus, 59, as well as daughter Anna, 25, with model Angela Ermakova, 57, and Amadeus, 15, with his second spouse, 49-year-old model Lilly Kerssenberg.

In June, the commentator and 34 year old Lilian - who tied the knot in front of 150 guests during a lavish, three-day wedding extravaganza in Portofino, Italy, in September 2024 - announced they were expecting Zoe, their first child together.

Lilian - who lives in Milan, Italy, with Boris - showed off her blossoming bump in a khaki swimsuit as she and Boris jetted back out to Portofino for a babymoon in October.

Captioning an array of photos from the romantic getaway - which the tennis coach shared on his Instagram account - he wrote: "We follow the light … Enjoying the last rays of sunshine. Happy Sunday!!!"

In 1999, Boris and his first wife, Barbara, got married in Munich, Germany, but they divorced in 2001 after he had a one-night stand with model Angela, whom he met at the Nobu Japanese restaurant in London, in the same year.

In 2009, the sportsman and his second spouse, Lilly, said "I do" in St. Moritz, Switzerland, but they went their separate ways in 2018 after nine years together.

Boris met his current wife, Lilian, through mutual friends in Frankfurt, Germany, in 2018, and they became a couple the following year.

And he said they had an "instant intellectual connection" when they first met.

Speaking to the Sunday Times newspaper in September, Boris gushed: "She is obviously a very attractive woman, but I felt that from the first day we had lunch together alone, we 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."
