Usher's sons love his new fiancée.

The 36-year-old singer recently got engaged to his longtime girlfriend, Grace Miguel, and his children, Usher 'Cinco' Raymond V, seven, and Naviyd Ely Raymond, six, with ex-wife Tameka Foster, have already formed a close bond with her.

A source said: ''He can't wait to spend the rest of his life with her. His boys love her as well! She gets along with them great.''

The 'Voice' USA mentor, who began dating Grace shortly after his split from Tameka in 2009, proposed approximately 10 days ago.

The insider told E! News: ''They are extremely happy and the way it was done was very sweet and romantic.''

The 'I Don't Mind' hitmaker recently paid tribute to Grace, who is also his business partner, admitting she had helped him through some tough times.

He said: ''I have an incredible partner and manager.

''She has helped me through some of the hardest times in my life and my career. She's someone who's been able to support and understand all of who I am. Not just as a dancer or as a performer or as a singer, but as a humanitarian and a business man and as a person.''
