(entertainmentwise.com) - Jennifer Aniston is reportedly set to follow in the footsteps of her ex-husband Brad Pitt and partner Angelina Jolie by adopting a child. At almost 40, the Friends star is said to be considering going it alone after a string of failed relationships.A source says, "It's not that Jen has given up ever having a child of her own or the family she craves, she is just looking at all the options open to her."There are so many children in the world desperate for a good home and Jen feels like it might be time to adopt a little boy or girl. She's almost 40 now and is as passionate as ever about being a mother." These latest claims come three years after her marriage with Brad fell apart, supposedly over the fact she didn't want children. Brad - who immediately hooked up with Angelina after the split - began fathering Hollywood's biggest brood.
