Why the big secret? Justin Bieber and Selena Gomez go for lunch date but sneak out the back door looking grumpy

Justin Bieber and Selena Gomez have been dating for over a year now and have been seen making out in public and being openly affectionate with each other.
But the teen couple appeared coy as they left Benihana restaurant in Sherman Oaks, California yesterday.
The loved up twosome sneaked out of the back door of the establishment with the Baby singer seemingly trying to cover his face with his baseball cap.

Justin led the way and held Selena's hand as they walked towards their vehicle.
Selena didn't raise a smile and looked dressed down in grey jeans, a neutral-coloured sweater and sandals.
Meanwhile, the pint-sized pop star wore baggy sweats, a grey T-shirt and trainers.
There had been recent speculation that the pair had split up after they hadn't been seen together for a while and Justin's resistance about speaking of Selena during a recent trip to the Ellen DeGeneres show.

But the pair seem to be firmly together although they did not appear to be in the best of spirits.
However the teen lovers had a passionate reunion at Los Angeles' LAX airport last week after being away from each other a few weeks.
But the teen heartthrob has a lot to learn about the language of love.
Rather than greet Selena himself, the Love Song singer was met and escorted by a bodyguard to a waiting van that had Bieber inside it playing the video game, Mortal Kombat.

The Spring Breakers actress was surely glad to be home as she had been caught in a 5.9-magnitude earthquake in Bulgaria's capital Sofia last week while filming The Getaway.
Selena assuaged the fears of her fans in a tweet that came Tuesday afternoon.

'Thank you for all of your concerns!! Earthquake was scary but thankfully everyone is ok. Praying for Italy,'  she wrote on her Twitter profile.
From the look on the singer's face she had missed Justin desperately and the couple embraced passionately in the back of the van before speeding off into the night

Home sweet home: The pair have been separated for weeks

Selena looked shaken and flushed as she walked out to the waiting van.
Wearing a crocheted blue top, ripped jeans and sheepskin boots, the teen starlet admitted that she had been scared by the incident although no immediate deaths or injuries were reported.
The Getaway also stars Ethan Hawke and is a remake of the classic 1972 flick of the same name, which saw Steve McQueen and Ali MacGraw play the lead roles.

Bieber made something of a statement about his good fortune yesterday with a T-shirt that played up to his diva reputation.
The Boyfriend singer was seen stepping out of a recording studio sporting a top emblazoned with the words ‘Doing real stuff sucks’.
However Justin clearly does value his work ethic and posted on Twitter today: '[You] gotta put in the work if you want the results.'
Justin teamed the cocky T-shirt with an appropriate pout as he left the studio in California today.
The star was also wearing a pair of baggy charcoal jeans held up by a Louis Vuitton belt, a red baseball cap and matching Converse trainers.
