The six-time Grand Slam singles champion and Wimbledon-winner told the paper that Dutch model Lilly, 33, is three months pregnant.
“We didn’t want to hide ourselves because it’s good news,” Becker told the paper, adding that recently-published photos of the couple vacationing in Mallorca that revealed Lilly’s burgeoning belly were also a factor.
The newlyweds don’t want to know the baby’s sex before it is born.
“We want to let ourselves be surprised and will need to be patient until the end,” the 41-year-old said.
Becker has two boys with former wife, German actress and model Barbara Feltus, in the 1990s. He later fathered a daughter with another woman after an alleged sexual encounter in a hotel broom closet.
With his fourth child, Becker told the paper he hoped to be more present.
“I spent a lot of time with my firstborn,” Becker said. “With my second son and my daughter that was naturally less. And now I hope that I’ll always be there until the end.”
According to Becker, pregnancy is “the most beautiful thing in the world.”
