If Ashton Kutcher isn’t already planning to propose to girlfriend Mila Kunis, after the surprise party she threw for him over the weekend, he better be!

According to what sources close to the former That 70s Show co-stars have told Us Weekly, Mila put together quite a gathering of Ashton’s closest friends to celebrate his 36th birthday in style — at Hollywood’s La Poubelle French bistro.

“It was very small. Ashton has been going there for years and years,” the source revealed. “It’s one of his favorite spots, like home, so it was comfortable and they were well taken care of.”

So what was on the menu? T-bone steak, lobster, quail, braised rib and short rib — NBD.

“They had been planning it for awhile,” the source said. “Ashton didn’t want a huge thing but they got a good group together. He’s certainly changed from how he used to like to party years ago. This was more of a wholesome situation. They had a great time.”

Um, if you’re serving food like that, we’ll change the way we like to party, too.

“Mila gets along great with all of his friends,” the source added. “She’s like part of the crew.”
