During a rehearsal for the Uuden Musiikin Kilpailu (UMK) competition, hosts Melina 'Mellu' Mäkelä and Aino 'Aikku' Silkelä experienced an unexpected wardrobe malfunction when Mäkelä's black blazer button popped open while engaging with the audience. This incident was especially notable as it occurred during their debut appearance on the large stage at the Nokia Arena, putting them directly in the spotlight. Fortunately, Mäkelä stated that she was wearing a bra, so her breasts were not fully exposed, though the situation was nonetheless embarrassing.

Mäkelä elaborated on the mishap during their podcast 'Tyttöjen vessa', revealing that efforts had been made to prevent such an occurrence, including the addition of a special fastener at the breast area for support. However, the fastener failed on this occasion, leading to the unexpected wardrobe malfunction. This incident serves as a reminder of the pressures and unpredictability that come with live performances, particularly in high-profile events like the UMK.

Both hosts have a strong presence on the Ylex channel, and their candid discussion about this embarrassing moment highlights the human side of performing in front of a large audience. The mishap, while comical, adds an element of relatability to the otherwise polished world of music competitions, emphasizing that even professionals can face unexpected challenges while on stage.
