[Video] Justin Bieber & Selena Gomez Reunite for pal's Birthday Party

Selena Gomez and Justin Bieber just can't seem to get enough of each other no matter how many times they say they're finished for good.

On Monday night, the pair were caught on video looking cosy as they partied together at West Hollywood hot spot Bootsy Bellows.

The pair, who have had a tumultuous on-off relationship since 2010, can be seen in a short Instagram video shared by Bieber's BFF Khalil looking happy and relaxed in each other's company as they celebrate mutual friend Alfredo Flores' birthday in the club's private back room, where
a waitress brings him a cake and sparklers. Continue reading to watch video below

They just can't get enough! Selena Gomez was
back in the arms of on-off boyfriend Justin Bieber on Monday - first
enjoying an outing in Malibu before hitting West Hollywood hot spot
Bootsy Bellows for a pal's birthday

 The 21-year-old actress and singer can be seen standing closely behind her beau, dressed in a white top, her long dark tresses tumbling around her shoulders, her face beautifully made up and with a beaming ear-to-ear grin.

Bieber is acting the diva, wearing dark aviators despite being in a dimly-lit club, his look completed with a bright blue fedora, maroon T-shirt and gold chain around his neck.

Earlier in the day, the 20-year-old is reported to have reunited with his lady love for some fun in the sun in Malibu.

Plenty to be happy about! The 21-year-old appeared to be in great spirits,
laughing and smiling throughout the clip as she stood closely behind her
apparent on-again boyfriend, dressed in a white tank top, her face
beautifully made up, her long dark tresses tumbling down around her
shoulders

They enjoyed a ride together on Justin's Can-Am Spyder three-wheeler, with the Come & Get It hitmaker clinging on tightly to her man as he took control of the vehicle, cruising along the beach
with the same group of friends.

Indeed, a source tells Us Weekly that the couple are 'definitely full-on back together at the moment'.

'They spent all day riding together on a Can-Am Spyder on Sunset Blvd... Justin drove while Selena sat on the back holding on to [him],' they confirm. 'He was incredibly sweet with her and they looked super happy and in love.'

Another insider concurs that they certainly 'looked like a couple' and were 'all over each other' during their outing.

While the pair didn't surprise anyone - least of all their friends - by reuniting once more, another source close to the Baby crooner tells the publication not to expect them to be together for the
long haul.

What a diva! Despite being inside a dimly-lit club, the 20-year-old was
wearing dark aviators, while he completed his look with a bright blue
fedora, maroon T-shirt and gold chain around his neck

There's no denying it! The blurry, panning
footage clearly shows the couple looking comfortable in each other's
company as they help their pal Alfredo Flores celebrate his birthday

'It is always on and off. Same story, every other week, every year. Now they are together again, next week they won't be,' the insider spills rather pessimistically.

Though they add: 'They never stop talking, even when you don't see them together - that never changes. They fight, take a break and then get back together. No surprise that it happened once again.'

Just last week, the Never Say Never heartthrob posted an intimate black and white photo to Instagram in which he is being embraced by Selena, who gazes adoring into the camera, her
hand wrapped around his head, only his neck and 'Patience' tattoo visible.

The caption read: 'Our love is unconditional.'

He swiftly deleted it though in a rather telling move.

Boys' club! Earlier in the day, Selena is said
to have been present as Justin took his Can-Am Spyder for a spin on the
beach in Malibu with birthday boy Alfredo (left) and friend Quincy, seen
hanging on tight around his waist as he took control of the vehicle

The news that the pair are back together will no doubt come as a blow to Selena's mom and stepdad, Mandy and Brian Teefey.

Their disapproval of their daughter's relationship with the troubled star is said to have been the reason they were unceremoniously fired as Selena's managers back in April.

Indeed, the move came as a complete shock to them both, who found out about their dismissal through the press.

The concerned parents were reportedly 'vehemently opposed' to Selena reconciling with Justin, believing that his bad influence was the catalyst for the former Disney darling's rehab stint.

She spent two weeks at Dawn At The Meadows recovery centre in Arizona from January 5, with the facility specialising in people aged 18 to 26 who are 'struggling with emotional trauma, addiction or dual diagnosis concerns'.

However, her representative was quick to tell the MailOnline that Selena 'voluntarily spent time at Meadows but NOT for substance abuse'. 

An enduring love story: Back in March, the pair
shared a video as they performed a choreographed dance routine in a
studio together, which culminated in them passionately embracing up
against a wall, with Selena being lifted up by her beau
