Anna Ermakova, the child of the six-time Grand Slam champion and Russian model Angela Ermakova, is now 15 and has made her catwalk debut at Berlin Fashion Week.

The teenager, who inherited Becker's striking red hair recently signed with a German modelling agency and, this week, stormed the catwalk at Riana's autumn/winter 2015 show, albeit with a giant, inflatable poodle.

Becker, who only acknowledged Anna as his daughter after a public paternity case, posted a photo of the teenager on Instagram telling his 55,000 followers, "What a beautiful young lady #Anna #family #berlin #mbfw".

The liaison between the tennis star and Anna's mother was allegedly over "within five seconds" and, ironically, coincided with the end of his playing career.

The encounter cost him his marriage to his then wife Barbara, who was pregnant with the couple's second child at the time.

After it was determined he was the father he was forced to pay Ermakova $3.3 million.

She then went public with her story in a German tabloid.

"He pulled me into the cupboard. He was totally passionate," she said.

A claim the former world number one, who now coaches current world number one Novak Djokovic, refuted when he spoke out about the tryst.

"I don't know if a bathroom is a better place but it actually happened on the stairs between the bathrooms so there was no broom cupboard," he said.

"I live and learn. It cost my marriage, it cost for the next couple of years my private life but having Anna is not a mistake anymore. I have a beautiful daughter. I love her very much."
