Adam Levine's ex-girlfriend couldn't be happier about his engagement.

Although the 'Voice' USA mentor proposed to on/off girlfriend Behati Prinsloo just weeks after his fling with Sports Illustrated model Nina Agdal, 21, ended, Nina insists she has no hard feelings towards either of them.

She told E! News: ''I am extremely happy for them both of them. I met his fiancee many times and she is lovely.''

While Nina is a fan of Adam's fiancee, she admitted she isn't close to him anymore and doesn't even watch his show.

She said: ''It's not like I am boycotting it, I just have never watched that show.''

The gorgeous model is currently single and wouldn't say no to a date with serial model dater Leonardo Dicaprio.

She said: ''If I was f***ing hot and slamming like him, I would do it if I can get away with it! Why not?!

''But I am very single at the moment...I like a good time, a man to make me laugh and is nice to my friends and family, and if you have that, it just may work out!''
