The pair began dating in May 2010 and this August, it was rumored that Song, 23, was pregnant but neither have confirmed the news.

Earlier this week Song alluded to some good news when she tweeted, "My stomach is full of excitement! Big plans... big plans. You'll soon see," in a posting dated October 12.

Before hooking up, both were linked to other stars in the Disney galaxy. Cyrus dated former "Sonny with a Chance" star Demi Lovato in 2009 and Song had been romanced by singer Joe Jonas in 2008.

Song is known for playing socialite London Tipton on the Disney sitcom "The Suite Life of Zack and Cody," the show's spin-off "The Suite Life on Deck" as well as "The Suite Life Movie."

She made her foray into more adult roles in the 2010 movie "The Social Network," playing the girlfriend of Facebook co-founder Eduardo Saverin in the Oscar-winning film.
