Benny Blanco in Vegas As Selena Gomez Posts Pics Amid Bieber Being pregnant

Benny Blanco was in Vegas this week, betting a few bucks … and apparently not taking the couple-y pics Selena Gomez posted online … this amid the Biebers’ pregnancy news.

New photos and video, obtained by TMZ, show Benny sipping on a drink and making a few bets at the Wynn Thursday — right around the time Justin et Hailey Bieber announced they were expecting their first child together.

The reason that’s relevant … well, Selena posted some snaps of the two of them around that exact same time as well — kinda making it seem she was with Benny during the bombshell.

Take a look … there’s BB at the table, doing his thing and minding his biz. Other photos we got a hold of show him walking with an older woman — who looks to be his mother.

We’re told this Benny sighting happened around the afternoon — and that he was in the building from 3:30 PM to around 8 PM … with no Selena in sight.

Again, it’s NBD obviously … but what it suggests is that Selena might’ve intentionally posted those lovey-dovey photos of herself and Benny on the heels of the Bieber announcement.
