Leni Klum Towers Over Mom Heidi Klum's E.T. in Sexy Alien Costume at Annual Halloween Extravaganza

This year marks the 23rd time Heidi has hosted her Halloween extravaganza

Leni Klum is living up to her mom’s Halloween legacy!

The model, 20, dressed as a sexy alien to mom Heidi Klum’s 23rd Annual Halloween Party on Oct. 31, which took place at the Hard Rock Hotel New York.

Leni's costume consisted of black leggings, black thigh-high boots, and a sexy black corset. She also painted her whole body white, wore a white wig and rocked antennae and what looked to be face prosthetics and pointy ears. We're sure her mom was so proud. While posing on the red carpet with Heidi and her mom's husband, Tom Kaulitz, Leni towered over both of them (they were dressed in elaborate E.T. costumes).

Leni previously revealed that she and her boyfriend also went as Pamela Anderson and Tommy Lee for Halloween on Instagram on Oct. 28.

"Our version of Tommy and Pamela," the model captioned the post, in which she wore a blonde wig and seemingly had a temporary tattoo wrapping around her arm. Her boyfriend had letters printed on his fingers to appear like tattoos (spelling out her name) and wore a wild black wig.

Leni told PEOPLE before her first time at the party that her mom goes “all out” for Halloween. She said she had been asking to come to the party for some time.

The mother-daughter duo has had other sweet fashion moments recently. They posed together on May 23 at the Cannes amfAR Gala, which raises money for AIDS research.

The two juxtaposed each other’s outfits. Heidi wore a Lever Couture gown made of ruffled pink tulle that twisted in an asymmetrical shape around her body into a train. She wore matching pink heels and statement green earrings and styled her hair back.

Leni made a bold statement in a sheer black knit dress with black 3D flowers. She wore her hair half up and finished the glamorous look with a gemstone choker.

Leni has also had family fashion moments with, Seal, Heidi's ex-husband. In January 2023, they wore matching black outfits at the premiere of Shotgun Wedding.

Leni wore a strapless little black dress, which she paired with a bold red lipstick and red nails, along with a black clutch. Seal wore a black windbreaker with black pants and a white shirt.

Heidi shares three other children with Seal: Henry, Johan and Lou.
