Excerpt: Britney Spears and Ellen DeGeneres spread a little holiday cheer in L.A. last Friday.

The singer - who just turned 27 last week - and the talk show host hit the street in old-fashioned dresses to sing a few Christmas Carols.

Spears donned a festive red crushed velvet hoop gown, tartan shawl and bonnet for the outing, while DeGeneres chose a mistletoe-topped bonnet and green crushed velvet outfit. Both wore white gloves and big smiles.
