The relationship between Selena Gomez and Benny Blanco is so serious that she’s now introducing him to her fatherly figure TV costars Steve Martin and Martin Short.

TMZ obtained these photos of Selena and Benny interacting with Steve and Martin on the red carpet at the 75th Annual Emmy Awards at the Peacock Theater in Los Angeles last Monday.

As you may know, Selena, Steve, and Martin all star in the hit Hulu show, “Only Murders In The Building,” which was up for 11 Emmy Awards, but snagged only one statue for Outstanding Production Design For A Narrative Program (Half-Hour).

Eyewitnesses tell us … the meeting between the four celebs occurred just prior to the kick-off of the gala event. Selena was first to approach Steve and Martin on the red carpet, giving them big hugs before chatting with them a bit.

Our sources say she then introduced her record producer boyfriend, Benny, to her costars, while the three men shook hands and exchanged pleasantries.

Sources tell us everyone got along great and it seemed as if Selena was presenting her new beau for the first time to a couple of fatherly figures in her life. Of course, we can’t be sure if they had ever met before this encounter.

After talking amongst each other for about five minutes, the foursome left the red carpet to go inside the theater for the awards show.

Looks like Selena and Benny are going full steam ahead. Might there be an engagement in the lovebirds’ future? We’ll just have to see.
