The sexiest man alive, Chris Hemsworth as he not only officially joined Twitter but also guest hosted NBC's "Saturday Night Live," accompanied with by two brothers.

Australian actor, Hemsworth, who is best known for playing Thor in the Marvel Studios super hero films "Thor," "The Avengers," "Thor: The Dark World," and the forthcoming "Avengers: Age of Ultron," was last night's special guest host on NBC's "Saturday Night Live."

Hemsworth, who is the sexiest man alive according to People Magazine (and probably most actual people), proved his comedy chops as he thrilled viewers during his guest-hosting stint on SNL.

The actor kicked off the show by bringing out his real-life siblings, Liam and Luke during his opening monologue for a skit with actor Kenan Thompson, who was introduced as the "fourth Hemsworth brother" with Kate MCKinnon as their mother.

ScienceFiction noted that the night would not have been complete without a parody of Hemsworth's famous roles, Thor. In an "Avengers New Report," reporter Danny Powell (Bobby Moynihan) is on the scene as an anxious and unreserved Thor is celebrating a victory over Ultron as he sings Queen's "We are the Champions" and kisses the reporter on the head.

"Yeah, yeah. I've got to give it up to those robots. They fought hard but luckily, I'M THOR!." Thor commented on how it looked like Ultron was going to kill everyone.

According to E! News, Hemsworth turned on the hotness up to 11 by appearing shirtless in a skit besides taking part in two epic parodies - a much awaited spoof of the FOX series "Empire" and a mock news reports involving, "The Avengers."

Hemsworth's SNL debut comes just two months before the May 1 release of "The Avengers" Age of Ultron," in which he reprises his role as Thor.

As Chris prepared to host "Saturday Night Live," he joined Twitter giving everyone a big thumbs up. The Aussie heartthrob posted his first tweet from backstage at NBC's SNL. Chris looked remarkably slimmer as opposed to his bulked up Nordic alter-ego. According to News, Hemsworth's first tweet was retweeted over 7,000 times in just two hours and in the same period, he amassed 40,000 followers. Hemsworth himself has only followed about 30 followers so far, according to News.

No prizes for guessing his very first follows, Liam and Luke Hemsworth.
