With the impending arrival of twins, George and Amal Clooney are taking no chances - splashing out £12.5 on improvements to their home.

Hollywood star George, 55, and lawyer Amal, 39, have transformed their nine-bedroom mansion in Berkshire into the perfect place to bring up kids, complete with its own nanny's quarters.

The pair are expecting the new arrivals in June, it was announced this week.

The couple have reportedly spent £12.5million renovating their nine-bedroom mansion in Berkshire, with additions including a nanny's quarters

Now The Sun reports that the Clooneys have now installed a fence around the outside of their four-acre island in the Thames to prevent the children getting into the water.

They purchased Aberlash House for £7.5million in 2014.

Other improvements include the addition of 18 CCTV cameras, two pools and a film editing suite, so George can work from home rather than have to travel to the US.

The Hollywood star plans to be a 'hands-on-dad' The Sun reports.

George's longtime friend and frequent co-star Matt Damon, 46, was thrilled for the couple.

'I'm thrilled for him. She's amazing. He hit the jackpot. Just on every level. She is a remarkable woman. They're gonna be great. They're gonna be awesome parents. Those kids are lucky,' Matt told ET Canada.

Expectant parents: Amal Clooney is pregnant with twins, who are due in June this year, it was confirmed this week

A source told InTouch in January that Amal, who is of Lebanese-British descent, 'is pregnant with twins: a boy and a girl.'

The couple 'feel like they’ve hit the family jackpot' in light of the big news, the source told the magazine.

'When George and Amal found out it was twins they were surprised,' the source said, 'but also a little scared because they both had said that one was enough.

'But the news that it was a boy and a girl made them both really happy ... they can’t believe in just a few months, they’re going to have two babies.'

The news was announced by Julie Chen, a host of US chat show The Talk, who is said to be very connected in Hollywood.

Amal has been showing off a baby bump in recent weeks and appeared to be glowing and in good spirits when she was spotted at Barcelona airport last week with the Ocean’s Eleven star.

Amal enjoyed a couple of days in the city with George and his parents Nick and Nina as she celebrated her 39th birthday.

The notoriously private couple kept tight-lipped about pregnancy rumors when they first arose last month.

When work started on improving the home in 2015, a resident said: ‘I used to be able to enjoy a short walk along the river and through the village twice a day. Now I am reluctant to take my dog out because I have no idea what I will be faced with.

‘I have lived here for 20 years and never seen anything like this – there is a total lack of respect and disregard for us other residents and there is a really bad negative impact on our village.’
