Court documents were made public even during leaked text messages in which Lively allegedly compared Swift to one of her “dragons” while discussing creative disagreements with Baldoni.TMZ previously reported that sources close to the situation claimed Swift was frustrated after being embroiled in the high-profile legal battle. The singer was subpoenaed in connection with the case earlier this year before the subpoena was later dropped.Lively and Swift shared a close friendship for years, with the actress even making the singer a godmother to her children. Taylor also named her songs after Lively’s children: Betty and Inez.Meanwhile, the wedding festivities have officially begun in New York City with a closed-door celebration at MSG. Several stars were spotted arriving at the venue tonight for a cocktail party. While the women wore robes, the men showed up in suits, ready to party late into the night.Friday’s celebrations include a wedding, where the couple will exchange vows in an intimate ceremony. After that, there will be a grand wedding celebration that will start from 3pm and go on until the wee hours of the 4th of July.
