李玟在《我是歌手第四季》第3期中演唱了歌曲《Price Tag》，宝刀未老的她又唱又跳，仍旧气息均匀。并且李玟首开先河，与自己特地从香港带来的伴舞们燃情热舞，high爆全场。赛后李玟表示，这样做是希望给观众带来惊喜，“我觉得这不是一场比赛，而是让观众去enjoy整个过程，观众开心就好！”

从此次比赛可以看出，李玟状态仍在，但为何近几年淡出歌坛？李玟表示，是因为希望更多地陪伴老公和年迈的母亲，“妈妈一直是我最大的冬粉，现在妈妈年级大了，耳朵不太好，听不太到我（唱歌）……”李玟坦言一提到妈妈就想哭，数度哽咽。但也正是妈妈希望她来参加这个节目。除了妈妈的鼓励，李玟表示也被总导演洪涛的诚意所打动。她透露，导演组在前几季都曾邀请过她。筹备第四季时，洪涛更是亲自飞到香港与她见面，让她大为感动，并最终决定牺牲陪伴家人的时间和精力来参加比赛。
