Help needed to identify a song title and artist

The only lyrics I remember are:

You're my lover,
Undercover,
You're my secrect passion and there is no other.

Thank you Brenda Dawn

HELENA PAPARIZOU - MY NUMBER ONE (lyrics)

You're my lover, undercover
You're my sacred passion and I have no other
You're delicious, so capricious
If I find out you don't want me I'll be vicious

Say you love me and you'll have me
In your arms forever and I won't forget it
Say you miss me, come and kiss me
Take me up to heaven and you won't regret it

You are the one
You're my number one
The only treasure I'll ever have
You are the one
You're my number one
Anything for you 'cause you're the one I love

You're my lover, undercover
You're my sacred passion and I have no other

You're a fire and desire
When I kiss your lips, you know, you take me higher
You're addiction, my conviction
You're my passion, my relief, my crucifixion

Never leave me and believe me
You will be the sun into my raining season
Never leave me and believe me
In my empty life you'll be the only reason

You are the one
You're my number one
The only treasure I'll ever have
You are the one
You're my number one
Anything for you 'cause you're the one I love

You're my lover, undercover
You're my sacred passion and I have no other

You are the one
You're my number one
The only treasure I'll ever have
You are the one
You're my number one
Anything for you 'cause you're the one I love

You're my lover, undercover
You're my sacred passion and I have no other
