Katie Holmes picked up tons of flowers and goodies around LA today. She's got a big weekend to prepare for, since Suri is turning 5 on Monday! Katie has said that they will be celebrating with a tea party, and as usual, it looks like the decorations will be picture-perfect. Katie has said that Suri is planning her own bash, but that's just part of the little star's whole birthday month of April. Katie and Tom Cruise brought Suri to NYC earlier this week, where they took in a Broadway show, snacked on Magnolia cupcakes, and Katie read Letterman's top 10 list. Tom and Katie always make time for romance as well, and they earned a spot front and center in our ultimate celebrity wedding picture slideshow.
