Chris Hemsworth doesn't know whether his brother Liam has rekindled his engagement with ex-girlfriend Miley Cyrus.

The 'Thor' actor has remained tight-lipped on rumours claiming his younger sibling is romancing the 'Wrecking Ball' hitmaker again, 16 months after they split up, and is adamant he has no idea whether they have plans to get hitched.
When asked if the former couple are dating on 'The Kyle and Jackie O Show', Chris said: "Not that I know of mate."
However, the 32-year-old star - who has his hands full with caring for his children India, three, and 21-month-old twins Sasha and Tristan, who he has with wife Elsa Pataky - has admitted he's always the last to find out the details when it comes to his brother's personal life.
He added as he broke out into a laugh: "I would find out through the press. I find out last most of the time."
Meanwhile, Miley, 23, and Liam, 26 - who met on the set of 2010 movie 'The Last Song' - have sparked speculation they're talking wedding bells again after the singer was spotted wearing a huge diamond sparkler on her ring finger.
A source said recently: "Miley says she can't wait to be Mrs. Hemsworth and wants to get married as soon as possible, maybe this spring. She's wants the biggest wedding ever!"
And, to add even more fuel to the fire, the couple were spotted locking lips at a Golden Globes party at the weekend.
The couple, who lived together in Los Angeles, began dating in early 2010 and, after three years of on/off dating, they announced their engagement in June 2012.
However, their relationship was short lived as they called off the wedding in September 2013 and subsequently split up, but vowed to always remain best friends.
