Now that Tyga and Kylie Jenner have gone public about their relationship, the couple took every chance to engage in some PDA whenever they are together.

That's just what happened during their vacation in Mexico, still part of Kylie Jenner's 18^th birthday celebration, along with their close friends.

Photos published on Daily Mail

 showed Kylie Jenner and Tyga sharing a sweet embrace before climbing up the steps to a zipline.

On the hike towards the tower, the couple was also walking hand-in-hand.

"Kylie sported high top Converse All Stars, grey pedal pusher tights, and a white crop top as she wore her dark hair down over her shoulders," it said.

"Tyga was a bit more covered up with blue trousers, a button down Aloha shirt, and leather lace up shoes."

Tyga and Kylie Jenner were joined in their Mexico vacation by Kendall Jenner who also took her turn in the zipline by wearing a sports bra, Timberland boots and black tights. Her BFF, Hailey Baldwin, was also along for the ride. As her way of supporting Kylie Jenner's 18^thbirthday, the model was wearing a tight shirt with the words "King Kylie" across the front.

King Kylie is the "KUWTK" star's Instagram handle.

The published photos of their Mexico vacation came on the heels of the report that Kylie Jenner and Tyga were offered to do sex tape by Vivid Entertainment for $10 million.

And rapper Tyga, who was reported to be having money troubles since his albums were not well-received in the charts, is allegedly considering the offer.

"Tyga would knock Kylie out of the park in this sex tape and it would be wilder than Mimi and Nikko's. Sure, that shower scene was cool but Tyga's got bigger ideas than that," a source told Hollywood Life, referring to "Love & Hip Hop" stars Nikko Smith and Mimi Faust's sex tape also released by Vivid Entertainment.
