Naturally though, people are curious as to whether or not they have any plans to make a lifelong commitment to each other. If Liam isn't around to answer the question, why not ask his big bro?
While Chris Hemsworth was walking the red carpet at The Avengers' world premiere in El Lay on Tuesday, that's exactly what people couldn't help asking!
"They're like 21 or something…I can't see that happening. You have to ask him about his relationship, I barely talk about my own."
Short and sweet, but we'll take his word for it. Miley and Liam have NO PLANS to marry each other!
