Speidi were both dressed casually, with Heidi in jeans, a zip up jacket and black Ugg boots.

However, judging by their display on Celebrity Big Brother, they're more than a bit proud of being American.

Heidi and Spencer were all smiles as they were photographed leaving the airport with their luggage and an impressive display of duty free.

Heidi and Spencer looked very happy to be back. Copyright [WENN]After planning to spend a couple of months exploring the UK, Heidi and Spencer have headed back to the US because of Heidi's 'hair emergency'.

She revealed earlier this week that she desperately needed her hair doing by her own hairdresser.

Heidi and Spencer went back to the US for Heidi's hair appointment. Copyright [WENN]Heidi explained: "I have an emergency hair situation going on. Usually I get my hair done every three weeks and I'm at about seven weeks or so. I've had the same person for seven years - he's a British hair guru who perfects blonde so I have to go back and see him."

Only Speidi could get away with an excuse like that.

However, Heidi and Spencer are likely to be returning to the UK soon, after landing a one-off documentary called The Speidi Story set to air on Channel 5 next month. We cannot WAIT.
