Kristen Stewart wants on/off boyfriend Robert Pattinson to help her adopt a new dog.

The 'Twilight' actress, who has two pooches of her own, Cole and Bailey, as well as Bear and Bernie, which she shares with the actor, is hoping he will find a new friend for them while filming new movie 'Life' in Toronto to mark her upcoming 24th birthday.

A friend told ''Kristen asked Rob what his thoughts were about her adopting another dog for her birthday. Kind of like a gift for her and Bailey, because Bailey wants a friend. She's been like, 'If you see a rescue dog in Toronto and you think the dog would be a good match, adopt him and bring him back to LA'.''

Animal lover Kristen, who will celebrate her birthday on April 9, is still in contact with her 'Twilight' co-star Rob, 27, who ended their four-year relationship last year after he struggled to get over her brief fling with married director Rupert Sanders in July 2012, and she wants him to be involved in her birthday celebrations next month.

The source added: ''Kristen wants to celebrate her upcoming birthday with her close friends in LA, and she wants Rob to join them.

''Even though she hasn't seen Rob in the longest time, they still talk all the time. They text, Skype. They are both pretty much in the same place right now, just focusing on work and staying focused.''
