It's likely to be festive at the top of the Official U.K. Charts later this week, with Michael Bublé's Christmas and Tom Grennan's "It Can't Be Christmas" vying for #1 on the respective albums and singles tallies.

Bublé (pictured) would enjoy a seventh nonconsecutive week at the top if Christmas (Reprise) holds firm. Sabrina Carpenter's current #1, Short n' Sweet, will fall back to #2, while her Island labelmate Chapell Roan is holding at #3 with The Rise and Fall of a Midwest Princess.

Meanwhile, the release of SZA's S.O.S. deluxe edition, Lana, helps the RCA parent album rocket 28 spots back to #4. Billie Eilish's HIT ME HARD AND SOFT (Darkroom/Interscope) will nudge forward from #6 to #5.

Fontaines D.C.'s Romance is on track to climb 15-9, while Amy Winehouse’s Back to Black (#32) and Lana Del Rey’s Born to Die (#34) are likely to rebound back into the Top 40.

On the singles list, Grennan is locked in a close race with the current chart-topper, WHAM!’s "Last Christmas." Right behind are Mariah Carey’s "All I Want for Christmas Is You" (#3), Laufey's "Christmas Magic" (which shoots 19-4) and Brenda Lee’s "Rockin’ Around the Christmas Tree" (#5).

Kelly Clarkson's "Underneath the Tree" is poised for a new high of #8, which could be her first Top 10 in nearly a decade, and José Feliciano’s iconic "Feliz Navidad" is on the cusp of its first-ever Top 20 appearance as it rises 21-19.
