Is Ashton Kutcher and Mila Kunis secretly engaged after Demi Moore divorce?

Mstars has previously reported, That 70's Show love birds Ashton Kutcher and Mila Kunis are ready to take it up a notch in their relationship, and make engagement arrangements and annoucements,  after Kutcher finalized his divorce to actress Demi Moore.

But rumor has it; the two costars are already engaged, so there is no need for an announcement, or is it? Just one week after the announcement of Kutcher's divorce from Demi Moore was finalized, it's being reported that Two and a Half Men star Ashton Kutcher, is already engaged again.

Ashton has been dating Mila Kunis since spring 2012, with marriage rumors swirling around often.

Now, In Touch Weekly reports that Ashton asked Mila to marry him during the summer. "His whole family had come out to California for Mila's birthday, which was on August 14, and he did it then," a source tells the magazine. Mila was later spotted wearing a gold band on her ring finger.  

In Touch also says that any engagement had to be kept under wraps until the divorce between Ashton and Demi was done. The couple split in 2011, with Kutcher being the first to file for divorce in December 2012.

If rumors are true, what's the rush? Could the baby bump rumors be true as well?
