Before you answer this question yourselves, I know the answer already. Myleene Klass is attractive, she's smiley, she's pregnant, she has an ounce of intelligence – that's more than most TV presenters can muster in an entire lifetime. So why am I asking the question?

Last night I switched on the The One Show – which is weird enough in itself – then, after I was bored (after 4 minutes, 23 seconds) I found myself switching over to BBC2, where its Saving Planet Earth UK was in full swing. There was Myleene AGAIN. Is she taking over the TV? Surely her smiley, vacuous ubiquity cannot be a good thing.

So let's recap Myleene's sudden leap to omnipotency. She appeared on Popstars in Hear'Say and achieved moderate, if short-lived, pop success. Just when her career in the public eye seemed to be petering out, she undertook a masterstoke – she appeared on the career-rejuvinating I'm A Celebrity, Get Me Out Of Here. Soon pictures in the redtops of Myleene in various states of undress were a daily confection. Myleene Klass was back, and this time you sensed that she wasn't going to let her sleb status slip this time.

More presenting gigs, both on TV and radio, followed. Fast forward to The One Show and last night's double-take time.

Just a quick word about The One Show. It's toss.

You can imagine BBC execs when they sat down to shape this idea: "I know, let's do a show, a smorgasbord of a show, that has EVERYTHING in it so it pleases everyone all at once."

It's like someone has produced the TV equivalent of vomit – a spray of multi-coloured TV waste; stuff that's too dull, boring or irrelevant for any other TV show is here. Adrian Chiles battles manfully (and a preggers Myleene smiles away), but just look at what they have to link and discuss – the first item was a short thing on how to spot badgers in your back garden. Badgers. A piece on mortgage swindles followed next.

Over on the other side, it was even more surreal. Myleene was poking spiders, and shared the programme with ex-snooker World Champ Dennis Taylor, who was birdwatching. Myleene Klass and Dennis Taylor sharing the same bill. You couldn't make it up.

Anyway, back to Myleene.

A brief look on imdb and her TV credits this year reads like this: Would I Lie To You?, This Morning, Loose Women, We Love The Sky At Night, The Screening Room, Comic Relief and Happy Hour. Even Trojans are feeling lazy.

This culminated last night when she was on, simultaneously, on both main BBC channels. Surely this can't be a good thing.

Myleene. Here's my plea to you. I'm chuffed that your career has taken off, and you're getting work all over the shop, but please bear in mind that old saying: a little goes a long way.
