J Lo and Casper are Swingers

Casper Smart brings out the kid in Jennifer Lopez.

He is 18 years her junior and Jennifer Lopez's toyboy lover Casper Smart is certainly bringing out the more youthful side of his 42-year-old girlfriend.

The American Idol star looked like a giddy teenager as she and the 24-year-old got playful in Santa Barbara, California earlier this week.

The new couple celebrated the Valentine's Day holiday on Tuesday by exploring their childish sides.
