Ashlee Simpson Ross-Næss and Alicia Silverstone held court front row at the Christian Siriano FW/24 presentation inside the Plaza Hotel in Midtown Manhattan on Thursday.

The 47-year-old Clueless alum repped the 38-year-old designer in a strapless red midi-dress and bejeweled stilettos selected by her stylist Anna Schilling.

Alicia – whose close friend with Christian – wore her signature flaxen locks in waves around her shoulders for the New York Fashion Week festivities.

Silverstone wore a bronze eye shadow and blush with a vampy Cabernet pout.

Missing from the two-time Daytime Emmy nominee’s side was her 12-year-old son Bear Blu from her 13-year marriage to Christopher Jarecki, which amicably ended in 2018.

According to People, Alicia paid her final $12K in monthly court-ordered spousal support to the 47-year-old former S.T.U.N. frontman in January.

Silverstone will next play a mystery role in SNL alum Kyle Mooney’s NYE 1999 comedy Y2K, which premieres at the Southwest Film & TV Festival in Austin, TX on March 9.

Jonah Hill produced the $10M-budget R-rated teen flick which also stars Rachel Zegler, Jaeden Martell, Julian Dennison, and The Kid Laroi.

The Reptile actress – who went vegan in 1998 – devotes much of her time preaching the benefits of the plant-based movement through her blog, The Kind Life.

Alicia famously claimed in her 2014 book The Kind Mama that a vegan diet prevents postpartum depression as well as curing PMS, breastfeeding issues, and MS.

Meanwhile, Ashlee looked leggy in a black-patterned blazer maxi-dress, featuring a long feather-trimmed train, and matching T-strap pumps selected by stylist Natalie Saidi.

The 39-year-old singer-turned-socialite styled her dark red locks into a middle-parted updo for the Siriano fashion show.

Simpson’s complexion was fully contoured with dark liner around her baby blues and a nude pout.

Ashlee hasn’t released a song since Bat for a Heart in 2012 following her infamous lip-synching scandal on NBC’s Saturday Night Live.

Simpson originally began her career as a back-up dancer for her big sister Jessica Simpson before following in her famous footsteps as a reality star and pop star.

The Texan redhead and the California blonde were joined in the front row by actresses Sophia Bush, Melanie Lynskey, J. Smith-Cameron, and Busy Philipps.
