London, Feb 7 : Tennis superstar Serena Williams desperately wants to have kids with her rapper/actor boyfriend Common.

However, Williams is not sure if she’ll be a responsible mother as she once accidentally left her pet pooch behind after a training session on the tennis court, reports The Daily Star.

She says, "I would love to have a baby... But I have two little dogs I take care of and they''re so cute, but sometimes I forget them. One time I was in the locker room... I was busy and I left and I was in the car driving home and I was like, ''Oops!'' I definitely don''t need any kids because I forgot my dog."

She adds, "Every time I see a woman walking around pregnant, I''m like. ''Oh my god, I could never do that.'' How are you walking? I look at them and my back starts hurting!

"That''s as far as I''ve gotten with that (having kids) but eventually, maybe one day I''ll get there. That would be awesome." (ANI)
