Jessica Biel may have had husband Justin Timberlake as her date for the Vanity Fair Oscars after party, but to get ready, it was her son Phineas by her side.

Shortly after gracing the red carpet to celebrate Hollywood's biggest night of the year, the 7th Heaven alum gave fans a behind-the-scenes glimpse into her time in the make-up chair.

Jessica took to Instagram Monday and shared a video montage to show how the glamor magic gets made, starting off with a clip of her looking fabulously make-up free, getting her hair styled with long, straight extensions.

She then shared another short video, still in the make-up chair, in which her youngest son, who is three, is sitting on her lap, his blonde curly hair flowing over her cable-knit sweater. The Candy actress is also a mom to son Silas, eight.

More clips followed of Jessica's natural, glowy glam for the glitzy night out, before ultimately revealing her stunning look for the event.

For the star-studded party, Jessica dazzled in an Yves Klein blue gown by Stephane Rolland, from its Spring Summer Haute Couture 2024 collection, which featured a form-fitting silhouette, long sleeves, and a sheer, billowing cape.

She accessorized with a structured, snake-like diamond necklace and matching raindrop earrings.
