Sources have told OK! magazine the actress is expecting another child with husband Dean McDermott, revealing the baby wasn't planned but the mum-to-be is "really excited".

The insider says, "They've been through a lot... but they've proved everyone wrong and this is good news for them. They see it as a fresh start."

But her reps tell there is no new baby on the way.

A Spelling insider tells the site, "Everyone says she is too skinny. Then, when she gains weight, everyone says she is pregnant. It's ridiculous."
