Terms of the settlement have not been made public, but TMZ.com reports Baumgartner received more than was outlined in their prenuptial agreement.
Over the weekend, the 48-year-old beauty agreed to the terms of a three-page settlement letter. It is believed her request for US$850,000 in legal fees was removed from the arrangement.
Last month, a judge agreed with Costner’s proposed amount of child support for Cayden, 16, Hayes, 14, and 13-year-old Grace, setting his monthly payments at US$63,209 - falling short of Baumgartner’s request for US$175,057. She later reduced her request to US$161,592 a month and argued luxury living is in the teenagers’ “DNA at this point” as they are accustomed to lavish holidays and private jet travel.
