Lindsay Lohan is back on theMean Girls red carpet!

Lohan, 37, made a surprise appearance at the premiere of the new Mean Girls film on Monday night — 20 years after the premiere of the 2004 film in which she starred and the musical is based — marking a full-circle moment for the new mom.

The actress, who played teen Cady Heron in the iconic movie, hit the red carpet at the New York City premiere dressed to impress in a black cut-out Alexandre Vauthier design with an embellished crystal belt, teamed with Giuseppe Zanotti ankle-strap heels and Melis Goral jewelry.

Lohan’s hair was styled in relaxed, side-sept waves (get the full breakdown here) as she also sported pink lipstick and rosy blush.

At the N.Y.C. premiere of the original film 20 years ago, the then 17-year-old star stepped out in a look that was trending huge in the early aughts – a babydoll dress — and she likely had teens running to the mall to recreate her outfit.

Lohan wore a plunging white dress with a ribbon sash paired with white strappy sandals and bright pink lip gloss.
