Angelina Jolie and Brad Pitt are reportedly planning to adopt another child--an orphan boy from the Czech Republic.

Jolie, who is in the Czech capital Prague to film her latest movie Wanted, has become besotted with the child there after paying regular trips to a Catholic orphanage, according to British newspaper The Sun.

The publication also reports that Pitt has flown in to meet the child.

A source tells The Sun, 'Angelina celebrated her 32nd birthday yesterday and had told Brad she felt it was time to extend the family again.

'Her maternal instincts are in overdrive and she felt a bond with the kid straight away.

'She called Brad and said she had found a child who would fit in perfectly with the other kids.'

The couple already has three adopted children--Cambodia-born Maddox, Vietnam-born Pax and Ethiopia-born Zahara, as well as biological daughter.
