Liam Hemsworth (b. 1990) is an actor from Australia working in Hollywood since 2007. He's most well known for playing Gale Hawthorne in The Hunger Games film series, and has also appeared in The Last Song (with Miley Cyrus), The Expendables 2 (with Sylvester Stallone), Paranoia (with Gary Oldman), and Independence Day: Resurgence (with Jeff Goldblum).
In August 2015, Hemsworth made his first Instagram post from the set of The Muppets. In the photo, he caresses Miss Piggy's face and says, "Spent Friday with the most beautiful girl in the world. Kermit, #SorryNotSorry."
When he appeared on the show in the episode "Bear Left Then Bear Write", he didn't share any scenes with Piggy. Gonzo uses his picture for an online dating profile and recruits Hemsworth to sit in for him on his date with Debbie at Rowlf's Tavern. With Rizzo and Pepe's help, Hemsworth agrees, but ends up leaving on his own date with Debbie.
