Nick Lachey has publicly congratulated his ex-wife Jessica Simpson upon her new engagement.

The singer and her sports star beau Eric Johnson announced they're planning to wed over the weekend - a week after Lachey, 37, proposed to his girlfriend Vanessa Minnillo.

Asked for his comments on Simpson's surprise engagement, Lachey tells UsMagazine.com, "I will say the same thing I always say - I wish her the very best."

Before announcing her own happy news, Simpson revealed she "couldn't be more happy" for her ex-husband after he confirmed he'd proposed to Minnillo after four years of dating.
