Jennifer Lopez, Shirtless Casper Smart Are Hippies for Halloween

Jennifer Lopez and Casper Smart

Hippie Halloween chic!

Jennifer Lopez and Casper Smart may be on tour in Germany, but that didn't mean they had to skip out on Oct. 31 celebrations.

"Happy Halloween LOVERS!" Lopez, 43, wrote on her official website, posting images of her and dancer/choreographer boyfriend Smart in hippie attire. "My team and I had fun celebrating in Dusseldorf and Oberhausen!" Flashing peace signs alongside her tour crew, Lopez was all smiles as she posed next to Smart, who showed off his sexy abs and chest tattoo.

Touring Europe on her Dance Again tour, the mom of twins Max and Emme, 5, recently celebrated her one year anniversary with much-younger beau Smart, 25.

"BEAUcasperSMART BEAR!!!!!!!!!!!!!! Today is OUR's!! Thank you for sharing your beautiful smile with me everyday!" Lopez, who has over 12 million Twitter followers, wrote on Oct. 25.

Taking her romance with Smart public in March, former American Idol judge Lopez — who split from Marc Anthony four months earlier — says her man is one of a kind.

"He's adorable. But you already see that," the singer-actress told Vogue back in March, shrugging off criticism of their 18-year age difference. "He really is [sweet]. He's a good egg. I don't want to talk about it too much. It's my private thing."
