Brooklyn Beckham poses for semi-naked snap with Nicola Peltz in birthday post.

Instead of recognising Victoria’s 51st birthday on Thursday, Nicola then shared a publicity shot of Brooklyn having cupping treatment.

An hour after the ex-Spice Girl shared precious birthday snaps, her oldest son posted a series of photos of him and US actress Nicola at the Coachella music festival in California last weekend.

Brooklyn just wrote: “Made amazing memories this year” — and he was quickly flooded with more messages from confused followers.

Meanwhile, his brothers Romeo, 22, and 20-year-old Cruz did leave birthday wishes for their mum.

Brooklyn was missing from one of Victoria’s birthday snaps, showing her and Becks, 50 next month, with Romeo and sister Harper, 13.

Brooklyn and Nicola, 30, were also absent from the first of his dad David’s birthday bashes — held in Miami on March 30.
