Are Jennifer Lopez and Marc Anthony turning into boring suburbanites? The superstar duo recently moved into a huge new house in Hidden Hills, Calif., and according to a friend, the couple also interviewed to become members at the local Sherwood Country Club - and a witness wondered what ever happened to "Jenny from the Block." "J. Lo showed up looking like Jackie O," says the witness, "and Marc was wearing some ridiculous preppy style outfit - it was like they looked up what people wear to country clubs and then tried to imitate it." And it seems the real country club wannabe is Jennifer! "She did all the talking - Marc barely said anything," continues the witness. "It seemed clear that he didn't want to mess up, like it was really important to her." J. Lo is so at home on her new block, she's also planning to run for the local homeowners' association board. "Jennifer already wants to make some improvements to the neighborhood, so she's getting involved in the association," a friend explains. "She's attending meetings and wants to run for office during the next election."
