The two-hour show peaked at 9.7m (41.8%) at 10pm. The commercial network's reality show was up by 86% on the channel's slot average for the year so far of 4.9m (22.3%).
Friday's final was up by nearly a million viewers on last year's show, which pulled in 8.2m (35.5%) on 30 November, 2008, in a 9pm slot. In 2006, the final delivered 9.5m (41.6%) on 1 December.
This year's run of the popular reality show, hosted by Ant and Dec, has been a big hit for the channel with a series average of 8.1m (33.6%), the most popular series since 2005.
Last year's run averaged 7m (29.4%) while in 2006 it gained a series average of 7.7m (33.3%). This year's series though was some way behind the 9.3m (39.6%) that saw the 2005 series.

BBC1's best response, whilst I'm a Celebrity was on air, was Have I Got News for You with 4.4m (18.3%). The channel's following Gavin and Stacey at 9.30pm had 2.9m (12.2%).
