Amanda Bynes is refusing to have children until she is in her thirties - because motherhood will take up all her time. The 23-year-old Hairspray star, who has previously brushed off reports she's dating rappers Drake and Kid Cudi, is single after she was dumped last week by a mystery man.

And Bynes is adamant she has a few more years before she considers raising a baby, even if she finds the perfect man to settle down with.

Taking to her Twitter.com page, she writes, "I want to be a mom but not til I'm 30 and even if I get married b4 (before) then I still want to wait to have kids til long after I'm married. (Because) children are a lot of freakin work and I can't deal with that til I'm AT LEAST 30 "
