Mila Kunis’ pregnancy party

Mila Kunis celebrated her pregnancy at a baby shower this weekend.

The 30-year-old actress marked the impending arrival of her and her fiancé Ashton Kutcher’s first child at an intimate gathering on Sunday.

According to reports, Mila was joined by a small group of family and close friends at the occasion.

But Ashton was banned from the event as it was a girls’ only affair.

"It was very small and intimate. Just her close friends and family," a source told E! News.

The party, which was reportedly held at Mila and Ashton’s new $10million mansion in Beverly Hills, is said to have been without a theme.

However, Mila was inundated with gifts from guests at the top-secret bash.

It was recently revealed that Mila and Ashton are planning to wait until after the arrival of their baby before they make their way down the aisle.

“They’re not planning to get married before the baby is born,” a source told Life & Style magazine. “They have a lot going on right now. They’ve been focused on prepping for the baby and the new house. But they are really happy and in love. They can’t wait for their baby to arrive.”

And Mila admitted in a recent interview that it was only when she and Ashton started dating that she considered the prospect of getting married.

“I never wanted to get married. From the age of 12, I prepared my parents for no marriage," she told W magazine. "Then things changed - I found the love of my life. Now my theory on weddings is: don't invite anyone. Do it privately and secretly. My parents are OK with that. They're just excited that I said yes."
