Inside Coleen Rooney's son's Prime themed birthday bash worth hundreds of pounds

Proud mum Coleen Rooney has delighted fans by sharing a glimpse into her youngest son Cass' exciting fifth birthday bash on Thursday.

The mum-of-four, who shares her sons with her husband Wayne, took to Instagram on Cass's special day, to post a series of adorable photos of her youngest child enjoying his Nickelodeon's The Loud House-themed birthday.

Coleen, 36, not only treated Cass to a wild birthday bash, but she also made sure he was showered in a mountain of gifts, including a big box of Prime energy drinks - which are in peak demand at the minute.

Cass woke up on his special birthday celebrations to a huge pile of wrapped presents, a balloon display, and a stash of the coveted viral Prime drinks.

In recent weeks, the drink has become impossible for customers to get their hands on amid the growing demand in the UK.

The hydration drink that comes in a variety of flavours has become hugely popular among teenagers and children due to effective online marketing, flavours include Meta Moon, Ice Pop, Blue Raspberry, Tropical Punch, Lemon Lime, Orange and Grape.

Coleen took to her Instagram Stories to share a snap of her boys opening a box of the highly sought-after energy drink Prime by YouTube superstars Logan Paul and KSI.

The gift box also included Prime clothing and Coleen wrote alongside the snap: "Happy house... Thanks @prime."

Despite the viral drinks being sold out across the UK, with retail prices increasing, WAG Coleen managed to get her hands on a stack of them for Cass's special day.

In one of the sweet snaps posted to Coleen's Instagram, Cass posed in his Looney Tunes pyjamas in front of his huge pile of presents, which were wrapped in personalised paper with his face on.
