With just four days to go until she reaches her 21st birthday, Chloë Grace Moretz rang in the milestone early with boyfriend, Brooklyn Beckham, and a slew of other A-listers in Los Angeles.

Celebrating her big day with a luxe bash at Hollywood hotspot Beauty & Essex over the weekend, the Neighbors 2: Sorority Rising actress appeared to be overjoyed, as she reunited with her British beau after spending almost a month apart from each other.

While the birthday girl wowed in champagne-toned Prada coordinates with sequin and feather embellishments, her off-again, on-again boyfriend created a stir with a departure from his typical appearance, sporting a touch of smudged black eyeliner that matched Moretz's, pinstriped pants, and gray suspenders.

After mingling with guests, including Sasha Lane, Tia Mowry, Stranger Things’s Joe Keery and his girlfriend, Maika Monroe, as well as her Neighbors 2 co-star Kersey Clemons, the blonde beauty indulged in a piece of her five-layer cake.

Post-cake, Moretz changed into her second outfit of the evening: A high-neck LBD paired with a red lip and knee-high black leather boots.

The 20-year-old later took to Instagram to pen a message of gratitude alongside photos from the star-studded affair.

“Last night I had the most wonderful time celebrating my 21st birthday with the most special beautiful humans,” she wrote. “Thank you so much @beautyessexla for putting it all together and making my 21st birthday dreams come true :).”

Happy birthday, Chloë!
