Mila Kunis and Ashton Kutcher attended her brother's wedding together on Saturday (07.12.13).
The couple, who have been the subject of engagement rumours recently, jetted to St. Petersburg in Florida to witness older brother, Michael, 36, tying the knot with ballet dancer Alexandra Blacker, 29.
A source told People.com that the newlyweds met when Alexandra trained Mila to play a ballerina in the 2010 movie, 'Black Swan', and got engaged last December in San Diego.
Mila, 30, wore a blush-coloured, knee-length dress to the nuptials and later attended the couple's reception at the historic St. Petersburg Yacht Club.
The insider also revealed that Ashton, 36, and Mila presented the couple with a generous gift that will see them enjoy a 10-day honeymoon in Australia.
It was recently revealed that Kutcher, whose divorce from Demi Moore was finalised last month, is planning to propose to Mila over the festive season.
A source previously said: "Ashton and Mila have talked about getting married for quite a while. They're incredibly happy together."
The couple met on the set of 'That 70s Show' when Mila was just 14 and started dating in April 2012.
Mila's brother isn't the only person to find love during 'Black Swan' as her co-star Natalie Portman also met her ballet dancer husband Benjamin Millepied on the set.
