Rosberg celebrates F1 championship by singing 'Sex on Fire'

German driver Nico Rosberg is the Formula 1 champion for the first time in his career and he's right up there for all-time awkward celebrations, too.

After earning the title following Sunday's Abu Dhabi Grand Prix, Rosberg went to Twitter to thank his supporters - and sing along to "Sex on Fire" by Kings of Leon for nearly a minute and a half.

In the highly anticipated final race of the season, Lewis Hamilton finished first, but Rosberg entered Sunday 12 points ahead of his teammate and only needed to finish third, even if Hamilton won. The 31-year-old finished second, clinching the championship.
