¡Muy caliente!

Joshua Jackson and Lupita Nyong’o packed on the PDA durinf a recent Mexican birthday getaway.

The “Black Panther” star, who turned 41 on Friday, and the 45-year-old “Dawn’s Creek” alum were photographed celebrating Nyong’o’s birthday weekend Sunday in Puerto Vallarta.

In photos obtained by The Post, a bikini-clad Nyong’o clutched onto Jackson, who enjoyed a beach stroll wearing a pair of dark swim trunks.

They held hands as they ran into the waves and even wrapped their arms around each other for some steamy kisses, which looked straight out of a movie.

“They looked madly in love, like they just couldn’t get enough of one another,” an eyewitness told E! News.

“They looked madly in love, like they just couldn’t get enough of one another,” an eyewitness told E! News.

The source added that Jackson spoiled his Oscar-winning lady with a large balloon display and bouquet of flowers in their hotel suite.

Jackson and Nyong’o pair were first spotted attending a Janelle Monáe concert together in October following their respective breakups with Jodie Turner-Smith and Selema Masekela.

In December, the pair were photographed taking a romantic stroll in Joshua Tree, Calif.

Nyong’o announced her split from Masekela in a Instagram lengthy statement in October after dating for less than a year.

“At this moment, it is necessary for me to share a personal truth and publicly dissociate myself from someone I can no longer trust,” she captioned the post, adding she had been in a “season of heartbreak” due to the “deception from her partner.

“I am tempted to run into the shadows and hide, only to return to the light when I have regained my strength enough for me to say, ‘Whatever, my life is better this way,’” Nyong’o added.

Meanwhile, Turner-Smith filed for divorce from Jackson in October after three years of marriage. They have a nearly 4-year-old daughter, Juno, whose name was revealed in court documents about the split.
