Pregnant Mila Kunis' wedding to fiance Ashton Kutcher will be outshined by her ex-boyfriend Macaulay Culkin who plans to race the "Jupiter Ascending" star to the altar.

Apparently, the "Home Alone" star never got over Mila Kunis and is now marrying Jordan Lane Price even before the pregnant Mila Kunis can head down the altar with her fiance Ashton Kutcher, according to the National Enquirer.

Mila Kunis and Macaulay Culkin dated in 2002, E! News said, although they kept their relationship under wraps because of the principle of the actress to keep her personal life "as personal as I physically, mentally, possibly can."

They later split in 2011 because of Macaulay Culkin's reported drug problem. The actor has built himself another career and is now touring with his band The Pizza Underground.

National Enquirer said that Jordan Lane Price bore a striking resemblance to Macaulay Culkin's ex-girlfriend Mila Kunis.

"Macaulay is convinced that Jordan's the one for him. They are crazy about each other," the publication said. "The band may be a joke, But Macaulay's love for Jordan most definitely is not."

The insider added that both Macaulay Culkin and his girlfriend could be engaged in a few weeks in time for a summer wedding.

A pregnant Mila Kunis is also repportedly hoping a summer wedding with Ashton Kutcher which would be a tight race to the altar, according to Enquirer.

In the latest issue of The Sun, it was reported that the pregnant Mila Kunis wanted a low-key and intimate wedding to fiance and baby daddy Ashton Kutcher with only their family there. 

"She doesn't want to do anything showy or over the top," a source told Sun.

The "Jupiter Ascending" star and the "Two and a Half Men" actor are reportedly expecting their baby as Mila Kunis was spotted leaving a prenatal yoga class in Los Angeles, E! News reported.

Fiance Ashton Kutcher wanted a party in the south of France to celebrate their wedding, reported Sun, and the pregnant Mila Kunis is open to the idea "depending on how they cope with having a baby."
