The model announced her big news via her blog on Monday, telling fans that her and Jack's little girl Pearl can look forward to a younger sibling.

 'Jack and I are super excited to share with you all that we are expecting our second baby!,' she wrote underneath a picture of her with Jack and Pearl.

'I am in my second trimester, feeling great & trying not to eat everything in sight,' she added on her blog, which is titled The Raddest Mom.

Clearly over-the-moon about the new addition to the family, she wrote: 'We feel so blessed that our family is growing & Pearl will have a little brother or sister to play with. It’s  crazy to think that we will soon be a family of four!'

Leaving the announcement to his wife, Jack simply retweeted a link to her blog, with the self-explanatory words: 'Pregnancy announcement.'

The couple are regularly spotted out and about with little one Pearl, who was born last April, and they have both admitted that they've been enjoying every second of parenthood.

Jack recently wrote on Twitter: 'I feel so deceitful when I take Pearl to the Dr and she has to have a shot. One minute it’s all smiles then sadness.'

The couple married six months after Lisa gave birth in a simple ceremony in Hawaii at the beginning of October.

Jack's sister Kelly, who has recently become engaged to other half Matthew Mosshart, praised her younger brother last week for his ability to cope after being diagnosed with Multiple Sclerosis.

'He's amazing. He's unstoppable,' she told People Magazine. 'It's like it's not even there… He always reminds me that it's not just him that we're fighting this race for. It's the 2.1 million people living with it as well.'
