Mila Kunis Refuses to Say Whether She's Married to Ashton Kutcher

— -- Mila Kunis knows about the rumors circulating that she and Ashton Kutcher have secretly wed.

However, she's not ready to clear them up one way or the other.

"We could just be a plural," she told Ellen DeGeneres, when asked about the message Kutcher posted on New Year's Day, reading, ""Happy New Year, [Love] The Kutchers." "My daughter has his last name legally, so thus, there's multiple Kutchers."

Kunis, 31, and Kutcher, 36, confirmed their engagement last year. Several months later they welcomed a daughter, Wyatt Isabelle, whom Kunis describes as "a big girl."

"She's a really good baby. She was 9.5 lbs when she was born," Kunis said. "Because she was so big, she was like a hearty little thing, we skipped the newborn stage. So she was a good hearty eater and she slept will. Newborn never happened. Newborn diapers never happened, newborn clothes never happened. ... She's four months old and wearing six month clothing."

The actress also described Kutcher as "an amazing dad," who's a pro at diapering and swaddling the baby. Feeding Wyatt has largely been her responsibility, but Kunis gushed that she loves waking up to be with the baby.

"When I go back to work full-time and I have to have 17-hour workdays, I'm going to need somebody to come and help me because I can't do both, but because I'm in a very specific place in my life where I could take time off, I did," she explained. "I loved the fact that the first three months she and I were up every night, and I figured her out and she figured me out and she now sleeps in her own crib in her own room and I'll never have that time again so for me it was a really nice three months."

"The truest meaning of unconditional love is my child," she continued. "I thought I loved Ashton. I thought I loved my parents, my dogs. I was like, 'I know love,' [but] it's such a different aspect of it.... When she was born I was like, 'This is the most incredible thing that's ever happened.'"
