Los Angeles, March 7 (IANS): Singer-designer Jessica Simpson, who is pregnant with her second child, has no plans to have more kids. She thinks two children itself will lead to a lot of work.

The 32-year-old already has a 10-month-old daughter Maxwell with fiance Eric Johnson.

"I really hope that it stops. I think originally I had wanted three kids and now that I have one and another one on the way, I feel like I could stop here. It's a lot of work. Obviously it pays off and it's totally worth it, but it's a lot of responsibility," she said on a radio show, reports contactmusic.com.

But she quipped that she wouldn't be surprised if she becomes pregnant again, saying: "Accidents do happen!"

Simpson is exhausted juggling between motherhood and her pregnancy.

"Maxwell's a really good sleeper. For me, right now, the only reason parenting is a little bit hard is because I am so tired from this pregnancy. Maybe when I have two I will be less tired, but I don't know about that," she said.
