Bradley Cooper  was spotted solo yesterday leaving lunch in LA. He's been busy hosting his family in LA with the help of his girlfriend, Renee Zellweger, who was seen around town running errands with his mom. Things seem to be getting serious for these two — in addition to their quality time with his parents, they supposedly just bought a $4 million home in the Pacific Palisades  neighborhood of LA. Bradley's mother and father are even said to have checked out the house during their visit. Apparently the place needs a little work, so Renee and Bradley are making some changes so they can create their dream home for 2010. We're looking forward to seeing what comes next for these two in the new year.
