Billie Shepherd will not compete on this week's Dancing on Ice following a family bereavement.
ITV said the reality TV star, best known for starring alongside her sister Sam in The Mummy Diaries, would return the following week.
Last week, Shepherd, 31, and her professional partner Mark Hanretty, 35, landed a place in the upcoming musicals week with a routine to Spice Up Your Life by the Spice Girls.
A spokesperson for the show said: "Sadly due to a family bereavement this week Billie Shepherd is taking a break from the ice and won’t be on Sunday’s show.
"We look forward to her returning next week and send her all of our love at this sad time."
MailOnline reported that her grandmother Wendy had died.
The Mummy Diaries follows Sam and Billie as they embark on motherhood, while balancing busy careers with hectic home lives.
The pair originally found fame on The Only Way Is Essex.
The news of Shepherd's absence from this weekend's Dancing on Ice comes after Denise Van Outen, 46, had to withdraw from the show on Tuesday after partially dislocating her shoulder during training.
The presenter and actress fell during rehearsals for the series launch earlier this month and made her debut on the ice with her shoulder strapped up.
Olympic gymnast Amy Tinkler, 21, and her professional skating partner Joe Johnson are stepping in as replacements from this weekend.
