E! News has confirmed that former "That '70s Show" co-stars Ashton Kutcher and Mila Kunis are engaged.

Kunis was spotted out shopping wearing a sparkling new diamond ring, and sources say that the two are indeed planning to tie the knot.

Kutcher and Kunis have been dating for almost two years, although it did take them awhile to publicly acknowledge their relationship.

Kutcher had previously been married to actress Demi Moore for eight years.
