Scarlett Johansson hosted "Saturday Night Live" on May 2. This was the "Avengers" star's fourth stint as the host. The episode featured her as a sports reporter and a flight attendant, but the highlight of the show was the skit of Black Widow's movie trailer. (Watch the video below.)

According to E! Online, the 30-year-old's monologue had her singing and dancing to Donna Summer's 1975 hit "Love to Love You Baby." Johansson sings the song in a Céline Dion-like voice and tells the horrified cast members that this is how she gets her baby to sleep.

The episode also focused on the coverage of the Baltimore riots by featuring a sports analysts covering the Baltimore Orioles-Chicago White Sox game that was played this week without any fans in attendance. According to The Blaze, a commentator describes the Orioles loosing to the Toronto Blue jays by saying that Baltimore took an "absolute beating from the boys in blue." Johansson as the reporter also encourages fans to watch a Red Hot Chili Peppers concert by saying that after the game they should "Flea," referring to the bassist of the rock band.

"Saturday Night Live" also made fun of the lack of female-centric superhero movies by Marvel. The episode gave one of Marvel's most popular female characters her very own movie, complete with the kind of storyline people associate with "women films" - a rom-com.

The trailer for "Black Widow: Age of Me" shows Johansson's Black Widow as the stereotypical rom-com heroine: successful, smart, fashion-driven, a resident of Manhattan, and totally unlucky in love. When she meets a suave new man, Ultron, her life suddenly seems to be coming together. However, the trailer shows that love is never easy when the significant other is a sentient robot bent on worldwide destruction.

The skit also has appearances by other "Avengers" characters including Captain America (Beck Bennett), Thor (Taran Killam) and The Hulk (Bobby Moyniham). The heroes play the standard issue rom-com supporting characters, from the cynical best friend to the goofy guy with a heart of gold.

The show also featured a skit on the Mayweather vs. Pacquiao fight, which was aired at the same time. "SNL" decided to air a bootleg version of the fight’s feed saying that “One of the guys on our crew knows a guy, who has a friend, who was able to steal the Pay-Per-View signal.” (Watch the video below.)

The musical guest was Wiz Khalifa, who performed "We Dem Boyz" and "See You Again."
