Actor Ashton Kutcher, and his main squeeze, actress Mila Kunis, reportedly have a little bun in the oven, who is due out in October. Though twin genes apparently run in his family, the couple is said to be with just the one child.

However, it's been revealed that there is another woman who is also pregnant with a Kutcher baby. Are they being Punk'd?

On Sunday, the engaged couple was spotted walking their two canines in the Los Angeles neighborhood of Kutcher's reportedly $10.8 million mansion. The lovebirds, who'd recently returned from their stay in New Orleans, appeared to be in chill mode as they strolled along, wearing matching sweats. "Stepping out: Ashton Kutcher and Mila Kunis enjoy a sedate walk on Sunday," said the Daily Mail on April 21. "Taking the lead, 30-year-old Mila looked rather weary as they walked the wealthy street with their pooches, less than 24 hours after they caught a flight back to LA from New Orleans."

Likewise, reports tell that the funny pair were in the "Who Dat?" city spending time with 36-year-old Kutcher's big sister, Tausha. So, she is the other woman who is also pregnant with a Kutcher baby, and is expected to bring her bundle of joy into the world this December.

Moreover, while exercising his pups, Kutcher was snapped "sporting a healthy growth of beard," before heading back behind the gates of his 9,400 property in the Hollywood Hills. Purportedly, he stole the home from right under Justin Bieber's nose. The Daily Mail revealed, "he'd initially been renting for $50,000 a month after hearing of singer Justin Bieber's plan to buy it outright," and that the actor once exclaimed to Jimmy Kimmel, "'I was like 'I don't want to lose this house. He forced me to buy a house.'"
