A brand new Britney Spears showed up at Jim Carrey and Jenny McCarthy’s Generation Rescue Event this weekend. Her first public appearance after a long period of time was really glowing and the event unveiled a Britney perhaps looking better than ever.

The association is committed to researching autism, in the attempt of disclosing parents the truth about the prospective reason for their child’s Neurological Disorders, so that they can be able to concentrate upon appropriate treatments.

A person who was also present at the fundraiser informed People magazine that Britney Spears appeared to be “really happy” and, in spite of the fact that she spent most of her time with her assistant Brett and did not speak much, she “smiled and clapped during the video about autism”, according to the event attendee.

Last week, Britney’s custody battle finally ended, as she reached a settlement with her ex husband, Kevin Federline. Although her former dancer and spouse obtained sole custody of the children, Britney was allowed to visit her two sons, Sean Preston, 2 and a half years old, and Jayden James, aged 1 year and a half, three times a week, including two overnights. However, the agreement implies that Britney has to pay Kevin Federline $20,000 a month in child support, a boost from $15,000.

Other stars who were present at the fundraising event were Hugh Hefner and the three Girls Next Door (Kelly Madison, Kendra Wilkinson and Bridget Marquardt), plus Charlie Sheen and his new wife Brooke Mueller, and Robert Rodriguez with Rose McGowan, according to People magazine.
