The 35-year-old had the procedure - which took her from a 34DD to a B-cup - last month, according to the Sun. which also reports it was the mum-of-three's third operation.
"She had the op three weeks ago and is very pleased with the results," a source tells the paper. "After the op she came to London for business then went to France to heal properly in private."
Victoria apparently had her first enhancement at a London clinic in 1999, going from an A-cup to a D. She then had her chest increased again, this time to a 34DD, two years later.
A spokesperson for the former Spice Girl declined to comment on the reports.
