'Identity Thief' Star Melissa McCarthy
The 'Identity Thief' star - whose weight recently came under fire by a US movie critic - will return to present the NBC comedy sketch show on April 6 for the second time in two years after winning rave reviews for her series debut in October 2011.

The 42-year-old Emmy-winning actress - who began her career doing sketch comedy with the Los Angeles improv troupe 'Groundlings' - previously reunited with her 'Bridesmaids' co-star Kristen Wiig on the show for a hilarious skit about an inappropriate office worker who sexually harasses a co-worker played by Jason Sudeikis.

Melissa has kept a relatively low profile since veteran film critic Rex Reed trashed her role in 'Identity Thief' last month calling her "cacophonous" and "tractor-sized" and blasting her as "a gimmick comedian who has devoted her short career to being obese and obnoxious with equal success."

It was recently announced that Justin Timberlake will host 'Saturday Night Live' for the fifth time next Saturday .

The 'Suit & Tie' hitmaker - who recently made his long awaited return to music following a hiatus to focus on his movie career - will also perform on the show as he gears up for the release of his new album 'The 20/20 Experience' on March 19.
