Christina Aguilera -- Finally Free ... Of Ex-Husband's Junk

Christina Aguilera finally figured out a way to get her ex-husband's lingering crap out of her life -- by putting the house up for sale.

Jordan Bratman -- whose marriage with Christina officially ended way back in 2011 -- showed up to Christina's Beverly Hills pad today with moving trucks ... to clear out the rest of his belongings ... now that Xtina listed the place for sale.

It's a glorious day for Christina, because as TMZ previously reported ... when she and Jordan first split he took his sweet time moving out. Fact is ... Christina and her lawyer put the heat on 2 years ago, and Jordan moved most -- but not all -- of his stuff out 2 years ago.

In fact ... months after the couple split Jordan, Xtina and her NEW boyfriend were all living in the family home as one big awkward family.
