Let It Shine premiered to an audience of 6.3 million viewers between 7PM and 8:25PM back on January 7 before dipping to 5.3 million viewers for the next two weeks.
Last Saturday's fourth episode saw a rather sudden drop with the show falling almost a further million viewers to 4.6 million. This week the show moved from the auditions to it's next stage and saw a slight increase, rising to 4.7 million viewers.
However it wasn't enough to catch up with The Voice UK over on ITV.
The Voice, which used to air on BBC One, made its debut on ITV for series six with 6 million viewers last month, putting it behind Let It Shine at the time.
However while Let It Shine has dropped viewers, The Voice UK has stayed much more stable across its first five weeks of auditions.
Last night's latest blind auditions had an audience of 5.4 million, down 200,000 on last weekend but the same as the Saturday before.
Once again the two shows overlapped for 20 minutes between 8PM and 8:25PM however that schedule clash will disappear for the first time since both shows started from next weekend, which is likely to improve ratings for both programmes.
Meanwhile, earlier in the evening on BBC One yesterday, Pointless dropped 1.5 million viewers against the Six Nations Rugby on ITV to 3.3 million viewers while after Let It Shine Casualty was up 400,000 on last Saturday with 4.7 million viewers.
Drama series Taboo posted its first increase of its run, up from last week's series low by 200,000 viewers to 3.6 million.
Over on ITV, Ninja Warrior UK jumped another 100,000 viewers week-on-week to a series high of 3.6 million while Through the Keyhole with Keith Lemon was steady with 3.2 million viewers.
