Mila Kunis and Ashton Kutcher's engagement isn't actually official, but all the clues are there.

There are reports that Mila has been spotted with an engagement ring and a bachelorette party.

According to reports, Princess Beatrice is planning to throw an extravagant bachelorette party for Mila Kunis. Rumors days Princess Bea booked a holiday at an exclusive resort in Cannes, France to celebrate Mila's not-yet-official engagement to Ashton Kutcher.

Princess Beatrice is sixth in line to the throne of England. She is the granddaughter to Queen Elizabeth. Beatrice is also best friends with Mila Kunis.

A source told the Daily Star newspaper: ''Beatrice seems almost as excited about the engagement as the couple themselves. Like all Mila's inner circle, she's known marriage has been on the cards for some time. But now things are official she wants to crack on with the celebrations. Bea told Mila she wants to take her for a pre- wedding shower in Cannes along with six or seven of their mutual friends.''

Beatrice has promised it will be a night to remember.

Kunis and Kutcher were seen kissing for the Kiss Cam at the L.A. Lakers game in January, and last week, they were spotted on a double date with  Ashton Kutcher's co-star on "Two and a Half Men," Jon Cryer and his wife, Lisa Joyner. Kunis and Kutcher were also spotted dancing Mila's uncle's birthday party at the Premier Russian restaurant in Studio City, California.

Laura Prepon said Mila Kunis and Ashton Kutcher are "an amazing couple," according to E! News. Last night, Laura Prepon was at the season-two cast preview for the hit Netflix series "Orange Is the New Black" in Los Angeles, and said "Yeah, I don't usually comment on my friends' personal lives," but they're an amazing couple."

A witness told about Mila's engagement ring, saying "It's a simple band with a round diamond," said a friend of the couple. "No baguettes, no insets. It's not ostentatious, like a Kim Kardashian ring. She doesn't need a security team with her to wear it. It's a lot like her and Ashton."

Ashton Kutcher and Mila Kunis met on "That 70s Show" where Kutcher played Michael Kelso and Kunis played Jackie Burkhart. The source said the pair have been talking about having children for some time now. The source said "It all came together when Ashton showed Mila a picture of a baby in a magazine and said he wanted to dress their baby in that style. Mila giggled as she cradled her stomach. She was glowing the entire time that she got her pedicure!"

Kutcher's divorce from Demi Moore was recently finalized and Mila Kunis and Kutcher are hoping to get engaged soon. Moore filed for divorce in November of 2011 after Kutcher reportedly cheated on her with Sara Leal, a 23-year-old student.

Mila will next be seen in the movie "The Angriest Man in Brooklyn" with Robin Williams, Peter Dinklage, Melissa Leo and Sutton Foster. The movie pens on Memorial Day weekend on May 23.
