Michael Lohan and Kate Major

Michael Lohan is not only engaged, but says he and fiancée Kate Major "practice at least four times a night" for a baby.

"Kate wants a baby. Since I'm getting no younger, we practice at least four times a night," he tells TVGuide.com about his fiancée, who claims to have had a previous relationship with Lohan's friend, Jon Gosselin. "We agreed that if she does get pregnant, one is enough."

Lohan, who turns 50 on April 25, has four children with ex-wife Dina, including Lindsay Lohan and aspiring singer Ali Lohan. Lindsay Lohan, 23, has told Us Weekly that her father's engagement makes her want to "vomit."

Gosselin, meanwhile, has denied he and Major dated, and she has said she despises him for the denial.
