Brooklyn Decker announces arrival of second baby with Andy Roddick in funny Instagram post

The actress and model jokes that she's 'fine' because she's having a good hair day despite chaos around her

Andy Roddick and Brooklyn Decker have announced they've welcomed their second child.

The tennis ace's actress and model wife took to Instagram yesterday to let fans know their news with a lighthearted post.

'A newborn, a toddler, a dog in a cone, a dog with a tumour but I'm having a good hair day so it's fine. We're fine. I'm fine', she wrote.

The photo Brooklyn chose to accompany her words shows the 30-year-old dressed in a denim shirt with her newborn daughter nestling against her chest.

Showing off her flawless complexion, Brooklyn goes without make-up and wears her blonde locks in a tousled natural-looking style.

The couple's poorly pooch can be seen sporting a recovery cone in the background of the shot.

Obviously excited to learn that the little one had safely entered the world, fans were quick to send congratulatory messages to the duo.

'The baby is here!! So happy for you. Much love to you all', said one.

Another added: 'Congrats Brooklyn & big hugs, that's a lotttt going on! Hope your pups will be ok! ❤️.'

A third follower found Brooklyn's upload particularly amusing, commenting: 'This is hilarious - love the 'I'm fine'. Inside joke with my friends. 💗 Wishing you and the animals well, and congrats on baby!'

Although they're yet to officially confirm the baby girl's moniker, Brooklyn and Andy, 35, are reported to have called the newest addition to their family Stevie.

The couple - who tied the knot in 2009 after getting together in 2007 - are already parents to a two-year-old boy named Hank.

Now retired from professional sport, Andy was keen to tell the world how much be appreciates his wife during an International Tennis Hall Of Fame ceremony last summer.

'Brooke, I don't know how you juggle it all', he gushed. 'You hear a lot of guys find it very tough to walk away from professional sports, but you are the reason my personal transition into a quasi-everyday life has been gratifying and full.

'Hank will someday realise how lucky he is, and our daughter that's coming will also realise she has the best mother on Earth.'
