Mila Kunis celebrated her baby shower on Sunday (27.07.14).

The 'Black Swan' star, who is expecting her first child with fiancé Ashton Kutcher this year, attended a top secret party in her honour in Los Angeles, where she was joined by a small group of close female friends.

A source told E! News: ''It was very small and intimate. Just her close friends and family.''

The celebration did not have a theme, but the brunette beauty, 30, opened a number of gifts for her unborn baby, rumoured to be a baby girl.

Reports initially indicated the fiercely private star would give birth in October, but rumours are rampant that she could be set to become a mother as soon as next month.

The former 'That 70s Show' star recently admitted she is very excited to marry her former co-star, 36, and is believed to be preparing to walk down the aisle next July.

She said: ''I never wanted to get married. From the age of 12, I prepared my parents for no marriage. 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 okay with that. They're just excited that I said yes.''

She added: ''We all get movie star crushes. I'm marrying mine.''
