Louis Tomlinson admits he was initially envious of Harry Styles' solo success.

Tomlinson and Styles were half of the former boy band One Direction.

Styles has enjoyed a meteoric rise since splitting from the group, going on to claim three Grammy Awards in the process.

Tomlinson shared that they suspected Styles will be the most successful of the group.

He refused to defend his former bandmate after he came under fire for a controversial Grammy award acceptance speech.

Several fans slammed Styles after he said, "this doesn’t happen to people like me” during album of the year win at The Grammys.

Tomlinson is keeping hopes up on a possible reunion between them.

He was recently spotted with a new fling following his split from his longtime girlfriend, Eleanor Calder.

Tomlinson has a son, Freddie, 6, with ex Briana Jungwrith.
