It turns out Tisha was the secret relative in question. 

Before finding out, though, Ellen explained how Pam reached out on behalf of someone in Ellen's 'past' who wanted to meet her.

While reluctant at first, Ellen's wife convinced her to go for it and meet the mystery person.

Though the tried to make arrangements to meet, things fell through.

'I always say it wasn't god's timing,' Ellen said.

Years passed before Pam got in contact again.

It was then at 49-years-old that Ellen learned she was adopted.

'... So I called back again and I said "Will you do a DNA test for me?" Let's flesh this out and get to the bottom of it.'

DNA proved that Ellen was in fact an adoptee.

It was quite the revelation for Ellen who told the ladies of The Real: 'I never knew. For 49-years, I never knew.'

After Pam shared a bit of her technique, Tisha revealed there were family members in studio waiting for Ellen.
