Mel C is said to be busy working on “Asia’s Got Talent”, while Victoria Beckham will be overseas with work commitments, reported Daily Mirror.
“Geri hoped to get the girls together as they’ve been a huge part of her life but Victoria has work commitments out of the country and Mel C. has already agreed to a TV role on Asia’s Got Talent, which is going to clash,” a source said.
“Of course they both wish her the best for her big day but won’t be able to be there in person. Fortunately, Mel B is heading back to attend,” the source added.
Halliwell, 42, and Formula 1 boss Christian Horner, 41, got engaged in November last year.
