Holly Madison has reportedly split from her husband.

The former 'Girls Next Door' star is said to have filed for divorce from Pasquale Rotella - who she married in September 2014 after three years together - ''weeks ago''.

A source told 'Entertainment Tonight' the former couple had simply grown apart and they remain committed to their family life and putting the interests of daughter Rainbow, five, and son Forest, two, first.

Neither Holly nor Pasquale have yet commented on the news.

Just six months after having Forest, the 38-year-old former Playmate admitted she and her spouse were keen to have more children.

She said: ''We definitely want more kids.

''We're going to wait a little bit, get used to this one, and then see what happens.

''I'm just going to see how many we have time for before I get too old, I guess!''

Holly loves being a mother to two but admitted it has been a big ''learning process''.

She added: ''It's been nice. Not a lot of sleep, but it's been nice. I just put the month aside to try and get a new routine with the two kids.

''I thought I'd been through the baby thing before with Rainbow and I'd got it down, but juggling with the two kids is something new ... It's a learning process for sure.''

And the 'Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny' author was delighted that Rainbow quickly adjusted to having a brother.

She said: ''Pasquale and I have been talking to her about getting a brother or sister long before I was even pregnant. We were trying to get the idea in her head, like, 'You're not the only one, so chill!' And we got some gifts from friends, like 'I'm a big sister'-type books. Those helped a lot.

''Their sibling bond is so valuable. It's so great to have that person who has the shared memories of growing up. It's her own little team. It'll be so cute to see them play. It will be really interesting to watch how that develops.''
