Don't forgeeeet! Britney's holiday skit with Ellen airs TODAY on The Ellen DeGeneres Show at 3pm ET on NBC. Check out the preview clip from ETonline, below. Brit looks adorable; she's got the whole Mrs. Claus thing goin' on. Ellen on the other hand... I love Ellen, but she sounded like I did last night during my horrendous Rock Band performance. Yikes. Jingle-j-j-jingle. Britney sounds so cute, love her. Can't wait to see it! What Christmas carol are you hoping they sing? My money's on "Winter Wonderland." Or "Grandma Got Ran Over By a Reindeer." Can't decide. xx♥
