Robert Pattinson and K Kristen Stewart looked glum to be returning from a long weekend in Montreal together when they flew into Los Angeles Airport last night.
The pair failed to crack even the tiniest smile - with Ms Stewart making an obscene hand gesture to greet onlookers instead.
The Twilight-starring couple - who are rarely photographed together - jetted into LAX with Stewart, 20, sporting a checked shirt that looked like one that her beau used to wear, along with trendy Rayban Wayfarer sunglasses, jeans and Converse sneakers.

He was also nonchalantly carrying a guitar on his back - presumably having made sweet music with his girlfriend all weekend.
Perhaps channelling moody teen Bella Swan in the Twilight movies, pale and interesting Los Angeles lovely Kristen seemed so annoyed to be back home she flipped her middle finger to cameraman as she got into a waiting car with her boyfriend.
Robert had romantically flown out to join Kristen in Canada as she's currently filming her starring role in a £28million adaptation of Jack Kerouac's 1957 'beat generation' novel On The Road there.
The eagerly-anticipated onscreen version of the cult literary classic is being executively produced by Francis Ford Coppola and directed by Walter Salles, the man behind 2004's Che Guevara biopic The Motorcycle Diaries.

It's an adaptation of a 1855 novel and sees Pattinson play a 19th lothario working his way up society and through a large amount of women.

The actor best known for his role as vampire Edward Cullen has also been busy shooting Water For Elephants with Reese Witherspoon.
In that movie, Rob plays Jacob Jankowski – an orphaned veterinary student who runs a circus. There he meets Marlena, played by Witherspoon, the beautiful star of the equestrian act.
And the star was recognised for his acting prowess at the U.S. Teen Choice Awards earlier this month, landing the Choice Movie Actor for his role in Remember Me.
Luckily for the balance of their relationship however, Stewart also won a Choice Movie Star gong and the pair won the Choice Movie Chemistry award.
They'll reprise their dark and edgy relationship in the Twilight Saga: Breaking Dawn Part 1 which is tentatively scheduled for release in November this year, with the second installment following in November 2011.
Let's just hope they lighten up in real life the meantime...
