This year's contestants seem to love a good onesie, and 16-year-old Ella has showed off her own baby blue version while out and about in central London.
Ella teamed her oversized babygrow with white high top trainers, a stripy bobble hat and a brown leather rucksack - which is a stark contrast to the glamorous get-up we're used to seeing her in.
We know everyone has dressed down days, but surely if your tipped to be the next Adele you might make a little more effort when the paps are around...
Meanwhile, fellow hopeful Rylan Clark was caught carrying a rather interesting customised cap with 'Rylan Is Reem' emblazoned on the front.
Perhaps it was a present from Joey Essex?
Although we wouldn't want to be seen in such a hat, we somehow have a feeling that he can pull it off. Rylan style.
