Narinder did present a series called 'Undercover Lovers' on some Sky channel (I think it was 'Trouble'), BusyBee - but it was hardly a high profile show.
Her problem is that she's tried
too hard to cash in on her BB 'fame' and as a result has ended up being branded as a Z-list celeb who'll turn up to the opening of an envelope.
I don't think she'll ever be taken seriously now as a credible presenter.
And I wholeheartedly agree with your statement about Helen and Paul - after the incredible media frenzy surrounding them after BB2, I think they've struck exactly the right balance between the occasional public appearance (mostly in Helen's case, sadly) and leading a normal, happy life together. BLTCS!
