4minute is just gathering more and more antis. After a short dance break with 2PM on last week's MBC Music Core, 4minute has moved on to SHINee for the ending of SHINee's "Juliette" performance. Before fans of both groups start jamming furiously on their keyboards, check out the performance from "Jailbait Generation" (except for SHINee's leader Onew, everyone in each group was born in the 90s).

Still, SHINee was smiling, 4minute was smiling, and Onew / Ji Yoon looked especially cute (not even Ji Yoon's sunglasses could hide her bright expression). Just like last week's 2:04PM collaboration, the actual amount of time both groups appeared on stage was pretty short. The managers probably realized that unless you're as popular as WonderBang, long collaboration performances only means more antis. In other 4minute news, they also performed "Hot Issue" on this week's Music Core.

That means it's just two more years until this becomes legal.
