Angel has "sexual feelings" for Noirin.
The 35-year-old Russian boxer revealed her lesbian lust for the Irish beauty in the 'Big Brother' diary room.
I love my underdogs and I always end up falling in love with the people you wouldn't expect. I'm a real softy
She said: "The last thing I expected in the Big Brother House was meeting someone. I've got really deep feelings for her. It's sexual feelings as well."
Angel confessed she was "confused and scared" and but hopeful her crush would lead to "something beautiful".
She added: "Lisa knows because she is a lesbian as well - she can smell it in the air."
Noirin and Angel, 36, have shared a passionate kiss as part of a drunken dare last night but Angel doesn't want to get her hopes up.
She said: "I don't want to call it love... yet."
Later in the same evening, Big Brother called Noirin into the Diary Room and asked her about her feelings for Angel.
The 25-year-old athletics champion said: "I get on really well with her. I used to take in stray dogs. I love my underdogs and I always end up falling in love with the people you wouldn't expect. I'm a real softy."
Angel is not the only person to fall for Noirin as Sree has already professed his love for her. Freddie - who changed his name Halfwit for the show - meanwhile, has admitted he "kind of" fancies Angel and would "definitely" have sex with her.
