David Hasselhoff gave a lucky wedding party a special surprise over the weekend by turning up unannounced at the nuptials.

The former Baywatch star was in Vienna, Austria on vacation when he stumbled across a wedding in the city.

And Hasselhoff treated the newlywed couple by posing with his arms around them for a snap.

Posting the image on Twitter.com he writes, "Just crashed a wedding in Vienna! Congratulations to the lovely bride and groom."
