Chris Hemsworth has opened up about his hilarious reaction to Liam Hemsworth's recent photos that featured him going shirtless and "flexing in tiny shorts." The Thor of the Marvel movies is totally bewildered by his younger brother's decision to post the photos, though he finds it pretty funny.

Chris addressed Liam's sexy photos during an interview with Entertainment Tonight on Tuesday, July 11 in New York City, where he spoke about being the new face of Hugo Boss' Boss Bottled fragrance. "You know what that felt like? That felt like a late Friday night, drunken kinda post," Chris said.

"And then the following morning he's like, 'I didn't. Did I? Oh no.' He can't delete it now," the 33-year-old actor jokingly added. He wondered why Liam had posted the photos in the first place. "I said to him, 'Was that intentional?' " he said. When asked if he would share his own photo in "tiny shorts," Chris quickly replied, "I don't think so, no."

During the interview, Chris also dished on competing against Liam "in a fun way" to stay in top shape. "People try to pair us off like there's this vicious competitiveness and, 'Arghhh! You got that part and I didn't,' and stuff, which isn't the case," he said. "Get us at home, playing cricket or football or surfing or something, and yeah, there's a great rivalry there - a very healthy one."
