Lacey Banghard may have thought she had it covered for the glamour stakes in this year's Celebrity Big Brother house, but along came Heidi Montag.

Brunette Lacey may have waited a mere three hours before taking her kit off, but half of Speidi wasted only minutes before stripping off and climbing first into the jacuzzi and then, on husband Spencer Pratt's invitation, into the CBB pool.

And blonde Heidi, 26, who has been married to the same man three times, showed off her incredible body in the cut-away swimsuit.

The US couple were allowed access to the house after jockey champ Frankie Dettori nominated the venomous couple to head into luxury to mix up the reality show.

And, presumably because The Hills star Heidi hadn't showered in the basement (and nothing to do with airtime) she quickly stripped down to an olive green bikini.

The married woman's bang on-trend swim suit was nothing like 20-year-old Lacey's first night strip - the former Page 3 idol simply took off her skirt and then swam in her underwear.

But the arrival of Speidi upstairs certainly caused some controversy.

Steps pop queen Claire Richards says to Rylan, 'This is just so weird; I’m still not sure what is going on.'

While in the diary room, Rylan told Big Brother that something feels wrong and he doesn’t know what is going on. 'It doesn’t feel like our house anymore.'

He adds that he doesn't think he can trust Spencer and Heidi, and misses Frankie.

Heidi is next in the diary room and thanks Big Brother, declaring what a great show this is, 'Oh my gosh, miracles happen!' She explains that Spencer doesn’t have too many positive thoughts for Rylan and that he’s 'a more selfish than a selfless person'.

Ironically in footage shown on Saturday evening Lacey comments that this is the happiest she’s ever woken up.
