These two are in fact “Ella’s Fellas”.
Thomas Rhett and Niall Horan recently had a co-headlining show in Nashville. And they did a co-encore set together, which included a cover of Ella Langley’s “Choosin’ Texas”.
Speaking of Ella’s hit, “Choosin’ Texas”, it just logged a 13th week at #1 on the Billboard Hot 100. She had two other songs in the Top 4. “Be Her” came in at #3 and “I Can’t Love You Anymore” with Morgan Wallen is at #4.
