Mila Kunis and Ashton Kutcher welcomed a baby girl on Tuesday, Oct. 1 – but the engaged couple were talking about having kids long before their first child was born. Prior to the pair making their relationship public in spring 2011, they were romantically linked on-screen on the hit Fox sitcom “That '70s Show.”

In 1998 Mila Kunis joined the cast of “That '70s Show” as Jackie Burkhart. The actress had been 14 years old at the time – and the series required that all actors auditioning be at least 18. With the little white lie, Kunis was cast to be the love interest of then 20-year-old Ashton Kutcher’s character, Michael Kelso.

While it wasn’t exactly love at first sight – as the two actors reportedly “couldn’t stand each other” – Kunis and Kutcher did share some sweet on-screen moments. Some fans of “That '70s Show” might remember a Valentine’s Day episode from Season 4 where Kelso donated his sperm in order to pay for a gift for Jackie. While Jackie loved her gift, she wasn’t exactly thrilled when she found out that her boyfriend had to go to a sperm bank in order to get it. She made her boyfriend go back to the sperm bank to get the “special men” (but actually “specimen”) back. The reasoning behind her action? Jackie wanted to be the only one to have Kelso’s baby.

“I care because if there are going to be any little Kelso babies … well, I want them to be ours,” Jackie confided in her boyfriend.

“Oh,” Kelso responded with a smile on his face. “You want to have my children?”

“Well, yeah,” she told him. “I mean, if you get rich and don’t lose your hair, because I love you.”

It seems like Mila Kunis got her wish in real life, but things did not work out between Jackie and Kelso on “That '70s Show.” Jackie began dating Steven Hyde (Danny Masterson) and Kelso got Brooke (Shannon Elizabeth) pregnant in Season 6.

TMZ broke the news on Tuesday afternoon that Kunis, 31, and Kutcher, 36, arrived at Cedars-Sinai hospital in Los Angeles around 6 a.m. Kunis was reportedly brought right into the delivery room with Kutcher by her side. “She’s here and healthy,” a source told People magazine of their newborn.
