On the latest recording of SBS “Strong Heart,” f(x)’s Sulli is reported to have allowed the MCs to measure her actual height, after telling how stressed out she was over her tall height.

“It really stresses me when people ask, ‘Did you grow again?’ People tell me I’m taller than 170 cm, but I’m really not,” Sulli said. Due to her tall height, especially apparent when she stands next to her fellow f(x) members, Sulli has earned the nickname, “Giant Baby.”

After her comment, “Strong Heart” MCs urged Sulli to measure her actual height on the show. The results, however, will be revealed on tonight’s show, which airs at 11PM KST.

Meanwhile, tonight’s episode of SBS “Strong Heart” will air under the theme, “Romantic Animation Special.” The special guests include SHINee’s Minho, Lee Hyun Woo, Kwanghee, Hong Suk Chun, and Han Hye Jin.
