Jennifer Lopez and Casper Smart played on a swing in Santa Barbara

The 42-year-old Jennifer Lopez looked like a giddy teenager as she and the 24-year-old Casper Smart got playful in Santa Barbara, California earlier this week.

Jennifer Lopez and Casper Smart celebrated the Valentine’s Day holiday on Tuesday by exploring their childish sides.

J Lo looked carefree and happy as she and Casper Smart played on a swing set by the ocean.

Casper Smart certainly looked his age in a pair of white and black board shorts with a complementary black hooded sweatshirt.

Jennifer Lopez still managed to look impossibly chic in a cream dress and long grey cable knit sweater as she joined her lover on the playground.

J Lo looked happy and in love as she hopped on the swing with Casper Smart for a full embrace and couldn’t resist giggling with glee.

After getting frisky on the swings, the pair took a walk on the beach to play in the surf.

They sat a distance apart on a large rock before moving on for a romantic hand-in-hand stroll.

Later, they carved a large heart in the sand with sticks which read “Jennifer + Casper.”

The couple showed off an additional romantic Valentine’s Day moment when Jennifer Lopez tweeted a black and white photograph of the two cozying up to one another.

Her eyes are closed in the snap while the shirtless backup dancer planted a kiss on her forehead.

However, Jennifer Lopez appears to have since erased the photo.

J Lo also spared some love for her fans on February 14, posting: “HAPPY VALENTINES DAY #JLOVE?RS!! I wish U ALL lots of love today and always! I l appreciate and love you all. #sweettweet.”

Jennifer Lopez and Casper Smart are now in Rio De Janeiro, Brazil, together, where they plan on attending the world famous Carnival festival.

They were seen today hanging out on the balcony of their hotel, waving to fans and taking pictures of Ipanema beach.

This time, they were on the same page fashion-wise.

Jennifer Lopez wore tight black skinny jeans, a black sweater and a cream and black plaid scarf looped around her neck .

Casper Smart was in black shorts, a striped black vest and a straw fedora.

They were also captured with Jennifer Lopez’s manager, Benny Medina, who posed for pictures with the diva that Casper Smart took.

Jennifer Lopez and Casper Smart have been dating since November, and though they seem happy together, there’s no chance Jennifer is rushing to remarry.

J Lo told Today show host Matt Lauer recently that she wasn’t planning on tying the knot again in the near future.

She said: “It’s not time to think about that yet. It’s still fresh.”

Jennifer Lopez has had more time to fully get over ex-husband Marc Anthony, with whom she recently shared a good humored appearance on the Ellen DeGeneres show.

She playfully “slapped” the father of her children during the interview, prompting him to joke: “That was assault on camera.”

Jennifer Lopez and Marc Anthony ended their seven-year marriage in July.
