Best random celebrity hookups

Athletes, reality stars, evil tech geniuses, actors and not-so-unwitting civilians all mixed this summer in some truly mind-bending combinations . . .

Matt Harvey and Lo Bosworth

Partying in the Hamptons while out with an injury, Mets star Matt Harvey was seen looking “cozy” with “The Hills” fourth banana Lo Bosworth. But a pal covering for the infamous dog Harvey, explained to us: “He’s known her for a few years . . . He’s single with a new puppy he’s obsessed with.” In other words, he’d rather snuggle with his puppy.

Nina Ag dal and Jack Brinkley-Cook

After Leo DiCaprio and Agdal, 25, split in May after a year, she rebounded with a younger man — Jack Brinkley-Cook, 22. Page Six revealed in July that the pair was dating, and they were seen smooching from Montauk to Manhattan. Cook is the son of Christie Brinkley, so he’ s spent nearly as many years hugging a supermodel as Leo has at this point.

Ben A ffle ck and Lindsay Shookus

Ben Affleck and Jennifer Garner’s on/off divorce saga f inally ended in April with both filing papers to end their marriage. Then, in July, the Batman actor stepped out for pi zza wit h “SNL” producer Lindsay Shookus. But perhaps it wasn’t a summer hookup at all? Some reports said the relationship actually began as far back as 2013, while others insist it just got serious.

Pamela Anderson and Julian Assange

One played Barb Wire, the other’ s stuck behind barbed wire. “Julian is trying to free the world by educating it. It is a romantic struggle,” the “Baywatch” babe gushed of the impossibly pale WikiLeaks founder. He’s said she’s “no idiot at all. Psychologically, she’ s very savvy .” She’ s visited him several times, and wrote a “love letter” urging his release.
