Lindsay Lohan in the house!

Recently sprung from rehab, the actress, 24, showed up at Sunday's MTV VMAs -- in a hilarious pre-taped segment that poked fun at her recent struggles with drugs and alcohol.

VMAs host Chelsea Handler, wearing a pre-show robe, encounters Lohan backstage.

"Hello, Chelsea," Lohan says.  "Have you been drinking?"

Handler denies it, but Lohan asks: "Then why is your ankle bracelet going off?" pointing a blinking device on Handler's leg.

See how the rest of the funny confrontation goes down in this funny video clip.
