To sing with vibrato you can try some exercises,
1) on a note ( G, for example) say 'hey', then two pulses 'hey-ey', then 3 pulses 'hey-ey-ey', then 5 pulses 'hey-ey-ey-ey-ey' then finally 9 pulses 'hey-ey-ey-ey-ey-ey-ey-ey-ey'
2) As you go along, try it on different notes, going higher each time. When you get to a high note, use the vowel 'ee' instead.
3) Practice with a metronome starting with a slow tempo & slowly increasing speed.
If you do it on a fast tempo, it sounds like a vibrato. All you have to do , as you get used to this, is controlling your vibrato with varrying speeds & depth to make it sound natural.
