Vettel yet to officially confirm he is now a father

F1 World Champion Sebastian Vettel is yet to confirm reports that he is now a father.

We reported earlier this week that the reigning quadruple World Champion's partner Hanna gave birth to a baby girl last Sunday.

News of their impending parenthood broke only last December, when Hanna Prater - rarely seen in the Formula 1 paddock - was reportedly eight months pregnant.

The birth of their child in a Swiss hospital caused a stir among his fans, but the famously-private Vettel has neither a Facebook page nor a Twitter profile, and thus has not confirmed the news via social media.

Now

Bild newspaper reports that the 26-year-old's management declined to confirm or deny the reports about Vettel's fatherhood.

What is clearer is that the Red Bull driver will have a new physical trainer in 2014, after working with Finn Heikki Huovinen in 2012 and 2013.

Before that, Vettel's well-known trainer was Tommi Parmakoski, another Finn.

All three Finns - Parmakoski, Huovinen and Kontsas - have links to the former McLaren doctor Aki Hintsa, who is close to Vettel. (GMM)
