So is it just a coincidence that as Heidi and Spencer become the most hated Celebrity Big Brother housemates ever, Lauren Conrad was photographed strutting around LA all smiles?

Lauren looked amazing in a collared peach dress teamed with strappy sandals, a black bag and oversized shades.

Anyway, moving on. Heidi and Spencer have seriously rubbed everyone up the wrong way after their behaviour in last night's Celebrity Big Brother.

Copyright [Channel 5]They went from being ecstatic about being saved from eviction, to shouting 'WE'RE GOING TO WIN!' at anyone who would listen, before engaging in PDA overload with something VERY dodgy going on under the duvet.

We can just picture Lauren Conrad watching the show in her onesie, laughing an evil laugh and pressing 'redial' to evict Speidi.

That or throwing up a bit in her mouth like we did after witnessing their sexual display last night. *shudders*
