after he was snapped collecting Elias from the airport. 
The German sports star shared tender embrace with the teenager as they shared an emotional reunion inside Heathrow airport.

Noah
 - who has previously been linked to Lenny Kravitz's daughter Zoe and 
Rafaela Sanchez - is now a  musician in Germany, while Elias is a

However
 in the summer of 1999, while Barbara was seven months pregnant with 
Elias, Boris fathered his daughter Anna during a one-night-stand with 
Russian model Angela Ermakova at Nobu in London.
When Barbara found out about the one night stand she moved to Florida and filed for divorce.
She fought their pre-nuptial agreement and managed to win more than £14million and the custody of both sons in a divorce court.

Although Boris disputed paternity, a
 DNA test in February 2001 proved that he was the father and he agreed 
to support Anna, now a budding model, and obtained joint custody in 
November 2007.
After moving to 
Switzerland and enjoying a few years out of in the media spotlight, 
Becker remarried in 12 June 2009 in St Moritz, Switzerland to Dutch 
model Sharlely 'Lilly' Kerssenberg
The couple have a three-year-old son named Amadeus Benedict Edley Luis Becker.
