The singer is aiming to spend a second week at number one with 'Domino'.
Jessie J is facing competition from David Guetta and Rizzle Kicks on this week's Vodafone Big Top 40.
The singer is hoping to hold onto the number one spot for a second week with new single 'Domino'.
But David Guetta's 'Titanium' is continuing to perform strongly after re-entering the chart last week at number four.
Rizzle Kicks' 'Mama Do The Hump, which has already spent five weeks inside the top ten, is also a threat to Jessie's crown this week, according to the midweek update.
Elsewhere, Swedish House Mafia's 'Antidote' is also performing well, while Cover Drive's 'Twilight' could pose a threat to the live top ten when it's released on Sunday (22nd January).
You can listen to the Vodafone Big Top 40 with Rich and Kat every Sunday between 4pm-7pm.
