Kourtney Kardashian posed with her rarely-seen son Rocky as she watched her husband Travis Barker perform with blink-182 in Sydney over the weekend.

The media personality, 44, has jetted Down Under with her drummer husband, 48, while his pop-punk band blink-182 have embarked on their Australian tour.

She even went to support Travis, 48, as she watched his show in Sydney on Saturday, taking her kids Penelope, 11, and Reign, nine – who she shares with her ex Scott Disick – with her.

Kourtney took to Instagram on Tuesday to give an insight into the family night out, revealing her infant son Rocky, three months, also came backstage at the Qudos Bank Arena.

The doting mother – who welcomed Rocky, her first child with Travis, on November 1 – flashed a huge smile as she posed with her little one’s pram backstage.

She showed off her laidback sense of style in a casual oversized sports T-shirt, worn as a dress to put her toned legs on display.

Kourtney gave herself a few extra inches in a pair of black lace-up heels and pushed her raven tresses back with a thick headband.

She wore a concert lanyard around her neck as she geared up for her husband’s performance, and was joined by her kids Penelope and Reign in the photos.

The two children were both seen photobombing her glamorous snaps and pushing their little brother Rocky’s pram around as their mother laughed.

The reality TV star was also seen gazing lovingly into the pram in another adorable shot. Rocky wasn’t shown in the snap, as Kourtney often keeps him off social media.

Referencing the amusing antics, Kourtney captioned the snaps: ‘The chaos [love heart emoji].’

Kourtney went to see Travis and his bandmates Tom DeLonge and Mark Hoppus perform in Sydney over the weekend, before they have jetted off to Brisbane for the next stint of shows

Kourtney remained in Sydney with her kids while Travis and his bandmates Tom DeLonge and Mark Hoppus toured around, performing in Perth, Adelaide and Melbourne.

However, the family have now all jetted off to Brisbane together for Travis’ next stint of shows and they have been seen exploring the local sights in recent days.

After staying in a $10,000-a-night five-bedroom Sydney mansion, Kourtney and her family are now reportedly bunking at a lavish Hotel in Brisbane, where suites can cost up to $1,800 per night.

After the three shows in Brisbane, blink-182 will then return to Sydney and Melbourne for newly-added dates at the end of the month before heading to New Zealand.
