Kylie Minogue and Cheryl Cole are among the stars lined up for guest appearances on BBC1's The Voice as the show battles a ratings slide.
The pair are poised to confirm they will perform during editions of the talent show as it reaches its climax.
The addition of the two chart stars comes as the programme suffered a further audience blow for its results show on Sunday - losing two million viewers in a week.
That came on the back of the last edition of The Voice being beaten by Britain's Got Talent for a second consecutive week.
Kylie and Cheryl are understood to be brought in for slots in the later stages of the contest over the coming weeks.
