After spending time apart due to strict work schedules, the two were spotted getting cosy at a party at Miley's L.A. pad earlier this month. "She was kissing him," says a witness. "They were definitely back on."
Her engagement ring was back on too. After going bare-fingered for the last few months, the 20-year-old singer rocked her 3.5-carat diamond at the Billboard Music Awards and Maxim's Hot 100 party.
Apparently the Hemsworth family aren't too happy about the love match. A source told the same magazine that Liam's brothers Chris and Luke staged an intervention with the Hunger Games star in April. Apparently, "They want him to end the romance for good."
With Liam's star continuing to rise and Miley placing all of her focus on music, will they ever make it to the altar? Place your bets below.
