Actually, they've been rumored to have been engaged for months, but all seems to be confirmed now. Mila stepping out with a huge blingy engagement ring is all the confirmation we need, really.
There's nothing more satisfying than seeing Kelso and Jackie (they played on-gain-off-again boyfriend/girlfriend on That '70s Show, where they met in 1998) together. Even though things didn't click for them then, they ended up back together and that's all that matters.
Mila dated actor Macaulay Culkin for some time and Ashton famously married a cougar. When Ashton and Demi Moore split in 2012, he got together with Mila and they've been inseparable ever since.
Mila posted a happy pic of the couple on Instagram the day before the big ring was spotted, writing, "I love you @kutcher78."
We can't wait to see if the That '70s Show cast reunites for their wedding.
