Miley and Liam’s relationship is on like Donkey Kong after the two dined together to rekindle their love!

It’s official! The Last Song can’t be sung on the relationship known as “Milesworth” — aka the on-again, off-again romance between Miley Cyrus and Liam Hemsworth. The recently reunited couple was spotted cuddling at the posh sushi restaurant, Katsuya, in Brentwood, Calif Sept. 16 — and one onlooker says they couldn’t keep their hands off each other!

“Miley and Liam looked so in love as they cuddled up on the couch in the Dragon Room. The couple clearly had lots to catch up on after their 2 week break!” a patron at the restaurant tells HollywoodlIfe.com of the hot date.

“Miley seems to have a sweet tooth – both for desert and her boy, she indulged in milk and cookies between whispering sweet nothings in Liam’s ear!”

Miley, 17, and Liam, 20 — who first started dating while they were shooting the movie, The Last Song, summer 2009 — recently broke up for a few weeks over the summer…but from the looks of it, they are back on and officially in love!
