After nine weeks at Number 1, Luis Fonsi's reign at the top of the Official Singles Chart with Despacito could be brought to and end this week.
Leading the way on today's Official Chart Update (July 17) is DJ Khaled's Wild Thoughts ft. Rihanna and Bryson Tiller, currently ahead by just 1,300 combined sales.
It could mean the producer claiming his second Number 1 on the Official Singles Chart, following his mega collaboration I'm The One with Justin Bieber, Quavo, Chance The Rapper and Lil Wayne, which hit the top spot for just one week back in May. For Rihanna, it would earn her a ninth Number 1 single.
Meanwhile, Calvin Harris' Feels ft. Pharrell, Katy Perry and Big Sean is on track to reach a new peak at 3, up one place, and Jonas Blue's Mama is holding firm, unmoved at 5.
New entries and high climbers
Little Mix's Power could be returning to its previous peak position at the Number 8 slot this week, currently up two places, while Rudimental and James Arthur's Sun Comes Up continues to climb, up three spots to 15 in today's update.
Irish trio The Script are set to land this week's highest new entry - their new single Rain is at 17, while Demi Lovato's latest track Sorry Not Sorry zooms 33 places to 26.
