From E!:

“Aside from Brit, her fiancé Jason Trawick and her father, Jamie Spears, around 20 kids—including Sophia Grace and Rosie from Ellen—enjoyed games and cake, but not the war excitement of opening presents. (That was done in the privacy of their own home.)”

A source said the party was a huge success.
“Britney was smiling ear-to-ear during the whole party and enjoyed watching her kids play with their friends. It was a really lovely occasion, everyone was in a good mood and in the spirit of the birthday. She looked overjoyed and at one point was singing happy birthday to them.”
They add, “Jason and Britney were beaming and couldn’t have been more proud of Jayden James and Sean Preston.”
