Britney Spears was doing well with her Vegas contract — raking in nearly $30 mil for 2 years … but we just found out, 50 shows into her run, her show was so successful she got an even sweeter deal.
Sources connected to Britney tell TMZ … the singer did indeed sign a contract for $310K per performance, and with 96 concerts over 2 years the total was $29.7 million.
But Planet Hollywood was blown away by ticket sales, which they said broke Vegas records.
