Get a room! Bikini-clad Kylie Jenner sits on Tyga's lap in sexy snap from couple's Mexican getaway

They are not shy when it comes to showing the world their affection for each other.

And on Tuesday Tyga, 27, shared a snap of a romantic moment with 19-year-old girlfriend Kylie Jenner as the couple cuddled up in Mexico last week.

In the photo the KUWTK star can be seen perched on her beau's lap as she shows off her figure in a black bikini with white embroidery along with matching choker. 

Flashback: Tyga shared this snap of himself with girlfriend Kylie Jenner on holiday in Mexico last week 

Kick it like Kylie in her Ellejay bikini

Kylie Jenner loves a good beach vacation and this time she brought along her boyfriend Tyga and bestie Jordyn Woods for a trip to sunny Mexico.

Earlier she was spotted in a mesh one-piece by Melissa Odabash, but here the LipKit entrepreneur switched things up when she donned a black and white bikini by Ellejay.

The top had a flattering triangle shape that was trimmed in a contrasting whipstitch design and the cheeky bottoms left little to the imagination. Kylie even donned a matching choker to finish off the look.

The couple spent a few days soaking up the sun at the Casa Aramara in Punta Mita, a luxurious villa owned and rented out by Girls Gone Wild creator Joe Francis.

Tyga's son King Cairo, four, was also with the duo as well as Kylie's BFF Jordyn Woods.
