Justin and Hailey's whirlwind engagement took everyone by surprise, but the two have been all smiles while photographed out since the news broke. The model has also been wearing her gorgeous diamond sparkler and she was recently seen buying the Biebs his own ring as well. It's going to be an exciting year for the lovebirds as they prepare for their future together.

"The wedding will most likely be in the fall," a source told In Touch. "And this will be a blowout event." It looks like they're ready to rock when it comes to preparations for their highly anticipated nuptials as well. "Hailey knows what she wants — an all-white, designer dress, bridesmaids, white doves… the whole thing," the source revealed. "Justin, of course, will make sure all of her dreams come true." We can't wait to see the happy couple tie the knot!
