Singer Bae Yumi and actress Kim Ah Joong's friendly moment was captured on Twitter.

Last week, Kim Ah Joong treated Yumi for a dinner in celebration of her new album that is coming out in five years, according to a source.

The two met in 2006 when filming "200 Pounds Beauty" when Yumi trained Kim Ah Joong's voice. Yumi then visited Kim Ah Joong in the filming scene and gifted food, and Kim Ah Joong cheered Yumi as well whenever she published a new album.

Yumi published the first single album, "Cheap Ring," on October 7, and Kim Ah Joon finished filming the movie "Only You" with Joo Won.
