There seemingly isn't any topic that's off limits to Gilbert Arenas.

Nick Young just wants the former NBA All-Star to stay out of his business... especially the saga between him and Los Angeles Lakers teammate D'Angelo Russell.

After learning that Arenas told TMZ Sports that he thinks Young and fiancee' Iggy Azalea would get over his alleged cheating and that he'll be there for the bachelor party, Swaggy P slammed the door shut on Gilbert's self-invite.

"@TMZ pls dnt ask ppl like Gil about me ... You gotta be invited first b4 you do a Bachelor party ...," Young wrote in a tweet that has since been deleted, as reported by TMZ. "@TMZ dnt ask Gil about me ... Tell him to worry about Laura ok."

Shots fired, man down. The Laura that Young is referring to is Arenas's ex, Laura Govan.

This all started when Arenas first commented on Russell secretly recording an alleged cheating admission from Young on video.

And Young seemingly hasn't been the same since.

Lakers coach Byron Scott told the media Monday that Young is “not here with us mentally" due to his strained relationship with Azalea as a fallout from Russell's recording.

What a mess.
