Jennifer Lopez Mocks Rihanna on Saturday Night Live

Jenny takes a swing at comedy.

Jennifer Lopez returned to the SNL block this weekend, and she brought the funny with her. The singer and actress hosted Saturday Night Live, participating in skits that spoofed the Olympics, the reality show Undercover Boss, and the song "We Are The World."

"The first time I was on this show was 10 years ago," said J Lo during her opening monologue. "Back then I was single and traveling around with a big entourage. But people grow up; now I'm married with two beautiful children."

Critics are calling Lopez's show one of the better SNL episodes of the season, as the cast seemed to gel around the superstar performer and actually produce funny material.

One of the most talked about skits featured Lopez poking fun at singer Rihanna in We Are The World 3: "There comes a time, eh!, when we heed a certain call, eh!" sang Lopez.

Other cast members mockedvarious famous contemporary musicians. Jason Sudeikis, for example, was Adam Lambert.

In another popular skit, Lopez and Fred Armisen played Telemundo broadcasters covering the Winter Olympics. "We don't understand these," she cried. "Es loca!"
