Why Nicola Peltz Beckham Wasn't at Mother-in-Law Victoria Beckham's 50th Birthday Party

The actress said she was spending time with her grandmother and was "so sad" to not be celebrating her mother-in-law

Victoria Beckham's 50th birthday party brought out the likes of the Beckham kids, Tom Cruise and even a Spice Girls reunion. But one familiar face was missing from the London get-together: Nicola Peltz Beckham.

The 29-year-old actress and wife of Brooklyn Beckham revealed on her Instagram Stories on Saturday, April 20, that instead of attending the party, she was actually spending some quality time with her grandmother.

In one upload, Nicola shared an image of her grandmother — who was her maid of honor at her and Brooklyn's wedding — smiling while receiving a hug, along with the message, "My world in my arms."

A follow-up image showed the Beckham family — sans Nicola — posing ahead of the 50th birthday gathering, as Nicola used the photo to note that she wished she could've joined her family at Oswald’s, the private members club in London where the festivities were held.

"I'm so sad I'm not there to celebrate you and hug you! Sending all my love from me and Naunni," she wrote to Victoria alongside a white heart emoji. "I miss you all so much!"

In the family photo, the Beckhams — Victoria and David, 48, their daughter Harper, 12, and their sons Brooklyn, 25, Romeo, 21, and Cruz, 19 — all dressed to impress while posing on a staircase.

Victoria rocked a sheer mint green gown and Harper wore a champagne-colored dress, while the boys all kept to tuxedos. While David, Brooklyn and Romeo opted for classic black, Cruz wore a standout all-white tux.

The family wasn't the only ones at the 50th birthday party. Other attendees included Gordon Ramsay, Salma Hayek-Pinault, Jason Statham, Rosie Huntington-Whiteley, and makeup artist Charlotte Tilbury.

During the get-together, a Spice Girls reunion got the internet talking when bandmates Geri Halliwell-Turner, Emma Bunton, Melanie "Mel C" Chisholm and Melanie “Mel B” Brown joined Victoria for a surprise dance routine to their 1997 single “Stop."

A clip shared by David showed the five women busting out the choreography for party-goers while they stood in the same positions as they did in their music video.
