Will Ferrell, Wife Viveca and O’Brien’s Final ‘The Tonight Show’

Conan O’Brien celebrated his very last night as host of “The Tonight Show” last night and according to nydailynews.com, actor Will Ferrell and his Swedish actress wife Viveca Paulin, were there to help see out Conan’s finale episode.

Shortly after O’Brien does a quick speech and just as the credits were rolling, Conan was joined on stage by the comedian and his wife Viveca, who were both dressed up in hippie outfits, to perform Lynyrd Skynyrd’s 1973 hit “Free Bird.”

Ferrell, who has starred in movies such as “Step Brothers,” “Bewitched” and “Elf,” donned a long blond wig, bell bottoms and a black cowboy hat, while his wife wore a floral head scarf and mumu that barely contained her pregnant belly.

While Ferrell was doing the singing, Beck Hansen and ZZ Top played behind him, as well as O’Brien who is an amateur guitar player. But as Ferrell hammed it up on vocals, O’Brien appeared to be having a hard time keeping up his strum.
