Lacey Chabert -- Holding the Mayo?

Former "Party of Five" fox Lacey Chabert was with a film crew in Malibu yesterday, and when asked what was being shot, her acquaintance quipped, "A mayonnaise commercial." If so, then it may look like this Hayden Panettiere ad.

The Bible Belt born belle also starred in "Mean Girls" with Lindsay Lohan, and had a few words for the girl who's detoxin' in Mormon hinterland: "I wish her the best, she needs prayers."
