Glee-ful Lea Michele displays her toned bikini body while frolicking along the beach in Mexico with boyfriend Matthew Paetz

It was fun south-of-the-border style for Lea Michele and her beau Matthew Paetz.

The 28-year-old Glee star was enjoying the sun and her guy during an affection-filled day at the beach in Mexico on Monday.

The outing allowed Lea to display her amazingly fit figure that was barely covered in a skimpy white and beige string bikini.

Hello Mexico: Lea Michele welcomed the warm rays and the attention of her boyfriend Matthew Paetz during a romantic Monday on the beach in Mexico

The couple, who met while shooting Lea's music video On My Way earlier this year, were obviously in the 'newness' phase.

They acted like a pair love-struck teenagers while playing a game of chase to the shore, kicking up sand along the way.

Lea swung her arms and swished her feet through the shallow waves without taking her eyes off Matthew.

Come on: Matthew, a 6 ft 2 actor from Indiana, pulled a laughing Lea to the water and she let him

It was Matthew - a 29-year-old actor and native of Indiana - who pulled the laughing star to the ocean for a dip, and although she feigned resistance she obviously liked the attention.

After a while the pair emerged from the sea and Lea ran her hands through her wet hair, showing off more of those taut abs as she did so.

All that exercise helped Lea and Matthew to work up an appetite and at one point during the day they were seen enjoying a casual outdoor lunch.

By then, Lea had pulled on a knee-length, paisley-print dress and slipped into a pair of flip flops.

If this New Year's Eve holiday doesn't say they're getting serious, the couple's previous trip to LA ink artist Dr. Woo for his-and-her tattoos should.

Lea took to social media on December 13 to share a picture of her getting a new design on her left hand.

'It was a @dr_woo_ssc kind of Saturday night... smilingthroughthepai,' wrote Lea, who apparently has 14 other tattoos.

'@dr_woo_ssc you are a genius!' Lea exclaimed alongside a snap of Matthew getting inked on his upper left arm.

Of course the couple's shows of PDA are becoming commonplace whether it be a casual stroll or a visit to the park.

Lea's previous relationship - to Glee co-star Cory Monteith - ended abruptly with the actor's tragic death from an accidental overdose on July 13, 2013.

Meanwhile, it has been revealed that Jennifer Coolidge is playing Brittany's mom on Glee.

Along with Ken Jeong, they will play the parents of Heather Morris' Brittany S. Pierce who is making a return to the show. 

Ken tweeted a photo of the gang along with the show's writer, Michael Hitchcock, back in November.
