Ali Lohan Covers Christina Aguilera's 'Beautiful,' Declares The Lohan Holiday Season Open (VIDEO)

Watch Ali Lohan cover Christina Aguilera's "Beautiful."

Season's greetings from Aliana Lohan!

Ho ho ho-han, children! Gather 'round as we kick off our holiday season celebrations! No, we're not talking about Christmas, Hanukkah, Kwanzaa, Yule, Saturnalia, Boxing Day, or even Malkh. (That's right, not even Malkh.) For today is the first day of the Lohan Holiday season, and Saint Aliana Lohan is here to start us off right with a cover of Christina Aguilera's "Beautiful." As tradition dictates.

OK no, but seriously, Lindsay Lohan's little sis took to her newly activated YouTube account on Monday night to post a vlog of her singing the legendary Xtina track. After a minute of major self-deprecation ("My mama and my siblings have wanted me to post a video of... myself showcasing my voice for a very long time, but I've been super, super chickenin' out, if that's a word"), Ali lets her Stripped flag fly. Girl's got some pipes, and a totally enviable lower register to boot.

Watch Aliana Lohan cover "Beautiful," and get #festive to the tune of "Lohan Holiday" after the jump.

And hey, with it being December and all, we'd be remiss not to include a shout-out to the title track on Ali Lohan's seasonally themed Lohan Holiday album from 2006. While other households may rock around the Christmas tree to Mariah Carey's  "All I Want For Christmas Is You" and Ariana Grande's "Santa Baby," we get #festive to "Lohan Holiday," "Groove Of Christmas," and "Silent Night" featuring mama Dina on the Bible. Season's greetings!

+ Watch Aliana Lohan cover Christina Aguilera's "Beautiful," and let Ali take you on a "Lohan Holiday" with her classic Christmas track.
