The heavy vehicles allegedly contain preparation for the couple's wedding which would be held at Lionel Richie's mansion in Hollywood.
Lionel Richie has fueled reports his daughter Nicole Richie will wed her fiance Joel Madden at his Hollywood estate after staff were snapped unloading a number of big moving trucks outside his home.
The socialite was rumored to be preparing to tie the knot with Good Charlotte rocker Madden this weekend and the increased activity in the crooner's front yard suggests the gossip is true. Security also appears to have been stepped up ahead of the planned ceremony - three bodyguards were spotted monitoring the area.
Samantha Ronson is expected to be a bridesmaid at the nuptials, while it is currently unknown whether Richie's other best pal Christina Aguilera will be too busy promoting her new movie "Burlesque" to attend.
Richie and Madden have been dating for over four years and have two children together - Harlow, two, and Sparrow, one. Sources claim daughter Harlow will serve as a flower girl at the wedding.
