Rumors have been swirling that Liam Hemsworth and his former fiancée, Miley Cyrus, have rekindled their romance.
To shed some light on the speculation, ET spoke with Liam's superstar brother, Chris Hemsworth, about the rumored reconciliation.
"I'm happy if he's happy, whatever he's doing in life," Chris told ET on Monday in New York City's Bryant Park at a gala celebrating his role as Australia's global tourism ambassador. "I can't confirm any of that but, you know, he's smart [and] he's happy."
While Chris remained tight-lipped about his brother's relationship status, the 32-year-old star opened up a bit more about his own Valentine's Day plans with his wife, actress Elsa Pataky,
saying he's got "lots of romantic stuff" planned.
"I can't tell you," Chris said. "Can't give it away, but it's going to be special."
Chris added that he'd "like to think" of himself as a romantic guy, adding, "[I] can't say I succeed all the time but it's the thought that counts."
Chris has been busy recently, taking on the role of Australia's global tourism ambassador, and he opened up about how his children -- 3-year-old daughter India Rose and 22-month-old twin sons
Tristan and Sasha -- have reacted to the family's life Down Under versus their life in California.
"They love it!" Chris shared. "Where we were in California, and being a part of the big city like that, [it was] very different to where we live in Australia. To be able to walk straight down to the beach and see nobody [is] something that they quickly acknowledge and appreciate."
"My wife loves it [too]," Chris added.
Recently, Chris appeared on Australia's Kyle & Jackie O radio show where he was asked about his brother's relationship with Miley and if the two former loves had reunited.
"Not that I know of, mate," Chris said at the time
, adding, "I would find out through the press. I find out last most of the time."
