Benzino doesn't appear to have been able to lure 50 Cent into a boxing ring, so he's settling for the next best opponent ... and, apparently, that's Aaron Carter.
Damon Feldman of Celebrity Boxing tells TMZ ... the former pop star is lacing up his gloves again this summer to fight the "Love & Hip Hop" star in the main event. We're told both contracts have been signed ... and they're slugging it out on June 11.

The match is set to go down at the Charles Dodge Center in Pembroke Pines, FL -- and Feldman says BitCoin Rodney is promoting it. Aaron is stepping up for 50 Cent ... whom DF and co. weren't able to book.

Despite the bad blood between Benzino and Fitty -- including the recent back and forth claims of outing attempts and alleged federal snitching -- it doesn't appear 50 was interested in settling their beef with hands ... dude's been mum on their public challenge.
Aaron, however, is coming back for seconds -- you'll recall ... he got pummeled by Lamar Odom last year, where he was greatly outsized. Benzino's also bigger than him, but it sounds like Aaron doesn't care ... and wants his shot to redeem himself.
