Ashton Kutcher and Mila Kunis Hugging at the Airport

Ashton Kutcher had his arm around Mila Kunis as they waited in line at the Hong Kong airport today. The duo made a stop at the San Francisco airport on Friday as part of their journey to Bali. Ashton and Mila are vacationing in Bali together following a string of romantic outings. They shared a date night in LA last week, met up for a movie, and even celebrated the Fourth of July as a duo. Rumors of their relationship first got started in April. Ashton and Mila haven't just been focused on their personal lives though, since they've also been busy with work. Ashton's been in character as Steve Jobs for Jobs while Mila started promoting Oz: the Great and Powerful and continued her run as the face of Miss Dior.
