Marry her! (If you love that sort of thing.)
The alternative is to ask her not do it if it bothers you. Bear in mind that the only person you can control is yourself. If she continues to burb away then you have to decide if it's a "deal breaker" for you.
There are only two ways to experience joy and peace of mind in relationships: we either get what we want or we learn to be happy with what we have. Best wishes!
