Tiwa Savage and Tee Billz: are they or are they not?

The full question is; are they or are they not - Married? Tiwa says they are not! Someone supposedly in the know sent me a mail a while back saying the loved up couple are actually married and their recent trip to Dubai was their honeymoon. But like I said before, Tiwa has denied she's married...and I believe her...but then Teebillz does something to raise my suspicion.

On his BB today, he wrote 'Happy birthday Mrs Billz'. Like we all know, today is Tiwa's birthday.
