Guerlain's Insolence ad campaign will appear as an opening ad during breaks and as a closer to the show.
The deal was negotiated by ITV's customer relations team and Jon Marchant at Team UK Media.
Stephane Euzen, Guerlain's UK marketing director, said the deal would help the brand to reach a younger audience and stand out in the competitive fragrances market.
The deal follows the signing of Toblerone for ITV1's Pushing Daisies, expected to be a key part of ITV1's upcoming schedule.
Meanwhile, ITV has also secured sponsorship from Nivea Deodorant for Rock Rivals, which starts airing this week.
