The rapper, who recently played in a charity golf tournament in Los Angeles, made his first public appearance since he was granted full custody of his two sons.
During an interview with People magazine, Federline said, "Been having a good summer, I can’t complain."
The 30-year-old father was granted full custody of his sons, Jayden, 1, and Preston, 2, earlier this month.
Federline has also been working on a new album, but didn’t reveal any details. "I don’t know, I’m going to make everybody wait on that," Federline said. "I’m not revealing any work strategy right now."
His last and only album, Playing with Fire, was released in 2006.
