The queen of petty, Blac Chyna, continues her reign.

Chyna and Lamar Odom posed for a sweet photo op on Wednesday night while at the I.Go Live app launch in Los Angeles. Ok, if you haven’t already had the “this is weird” reaction … let us help you.

Odom was the man once married to Khloe Kardashian … who is also the sister of Chyna’s baby’s daddy, Rob Kardashian.

The pair’s random run in, however, is just one half of the story. Let us continue.

Also in attendance, was Chyna’s other baby’s daddy, Tyga. We know, bizarre, right?! Tyga dumped Chyna years ago to start a relationship with teenage social media icon Kylie Jenner, who is also the sibling of Rob and Khloe.

Anyway, considering Rob and Lamar were once BFFs, we think Chyna knew exactly what she was doing when she posed for a snapshot with the former Lakers play. Just like she knew what she was doing when she posted a video last week of her alleged new boo kissing her on the forehead.

We should also note that Chyna and Lamar both arrived alone.
