Tori Spelling has given birth to a baby girl, while Jackass star Johnny Knoxville is also celebrating the birth of his second child.

Spelling and her husband Dean McDermott - who already have son Liam, four, and daughter Stella, three, together - were shocked but delighted when Tori had the baby yesterday, one week earlier than planned.

A source told Life & Style: "The baby wasn't due until next week, but it was an early present!"

However, the sex of the baby is sure to be a shock to Tori, 38, after she recently revealed she was expecting to have a boy.

She said: "My gut says boy, and we have a boy's name that we're pretty set on."

The couple may add another girl to their family at some stage as Tori isn't planning on stopping after her third child either.

She added: "Whatever we have, we'll go for the opposite on the fourth one. If we are able to have another child, that would be amazing!"

Recently, the busy working mum admitted she finds it hard to juggle parenthood and a career and questions her ability constantly.

She said: "I'm scared of screwing up my kids. I thought that once we were out of the baby stage, parenting would be a breeze. You just feel at every turn like, 'Whoa, am I making the right decisions, setting the right boundaries?'

"There are days when I struggle with wanting to be a full-time, stay-at-home mother, and feeling guilty about that because I work. One parent at school recently said, 'Oh you never go to anything.' That hit me really hard."

Meanwhile, Johnny Knoxville's wife has given birth to their second child.

Naomi Nelson and the Jackass star welcomed daughter Arlo into their family last Thursday, joining their 22-month-old son Rocko and Johnny's daughter Madison, 15, from his first marriage to Melanie Lynn Clapp.

Johnny tweeted: "Yesterday Oct 6th Naomi, Madison, Rocko & I welcomed a brand new baby girl into our family. Her name is Arlo & mommy & baby r doing great!! (sic)"

Johnny - who married Naomi in September 2010 - announced her pregnancy on Facebook earlier this year.

He wrote: "my wife naomi and i are super happy to announce that we are having another little bambino in the fall. my 15-year-old daughter madison is very excited about it, and her 16-month-old little brother rocko has, well, no clue. wahoo!!(sic)"

Johnny - whose real name is Philip John Clapp - previously revealed he "hoped" he was a good parent but had to rethink his approach when he once found himself "ordered to the ground" by police when he was babysitting Madison.

The 40-year-old actor said: "I hope I'm a good father. Sometimes I get excited and things happen and I'm trying to do good.

"I was babysitting my daughter and her friends, they were all at the house one day I set up the backyard as a shooting gallery with helium balloons and whatnot and we were having fun shooting the helium balloons when the cops burst in and ordered me down to the ground with guns.

"(Cops) came in my house! Apparently someone said there were shots fired."
