Mark Zuckerberg busted staring at Lauren Sanchez’s in-your-face cleavage during Trump inauguration

Eyes up, Zuck!

Facebook billionaire Mark Zuckerberg was busted apparently ogling at Lauren Sanchez’s cleavage during President Donald Trump’s inauguration on Monday, viral video shows.

The Meta founder appeared to glimpse down at the 55-year-old’s in-your-face décolletage as he was sitting beside her in the Capitol Rotunda ahead of Trump’s swearing in ceremony.

Sanchez, who is engaged to Amazon billionaire Jeff Bezos, caused a stir after showing up to the 47th president’s inauguration dressed in a risqué lingerie-inspired bustier and tight-fitting white blazer.

Zuckerberg’s own wife, Priscilla Chan, was sitting on the other side of him as the encounter unfolded.

Unlike Sanchez’s eye-popping fit though, Chan opted for pearls and a pale cardigan that was buttoned up to the neck.

Footage of Zuckerberg’s apparent wandering eye was quickly noted on social media — with some eagle-eyed viewers joking that maybe the Facebook titan “is human after all?”

“Mark Zuckerberg is ready to risk it all for Jeff Bezos’ fiancée at the inauguration,” another chimed in.

“What a dog,” one said bluntly.

Social media users were quick to rip Sanchez, too, for choosing to wear the revealing outfit in the first place.

The former TV reporter had unveiled the lacy number — which appeared to be an $1,800 Alexander McQueen satin-trimmed bustier — when she whipped off her white coat soon after finding her seat inside the Rotunda.

“Good grief, Lauren Sanchez. Put them away for one day,” one critic wrote on X. 

“Just when I was luxuriating in the beauty and class of [Melania Trump], in walks Lauren Sanchez wearing only a bra,” another said.
