Gwen Stefani and Blake Shelton went public with their relationship on Wednesday, but it was Shelton’s ex-wife Miranda Lambert who was turning heads with a newly-pink hairdo.

The 31-year-old singer seemed to be sending a subtle message about her ex-husband’s new relationship with his fellow Voice coach with her pastel ‘do. Stefani rocked pink hair for years as the lead singer of No Doubt.

Shelton and Lambert divorced quickly and quietly in July, while Stefani and Gavin Rossdale announced their separation in August. The latter recently settled their divorce and will share custody of their three sons.
