And she's a pretty lucky lady because she even wangled a hair sesh with Jay before the event to make sure her tresses were bang on trend.
Half-up topknot? Done.
The 25-year-old actress and mother to baby Matilda chose a stunning white trouser suit from prettylittlething.com for Jay's 'White Party' at the Birmingham hot spot on Sunday night (24 July).
She teamed it with a cropped black top, hot pink heels and a matching clutch, along with this season's must-wear berry lips, a Fake Bake tan and contoured cheeks that would make any Kardashian seethe with jealousy!
But it was her hair that really took our fancy at Reveal HQ.
Coiffed by the birthday boy himself, Helen went for a half-up topknot with soft, tumbling waves, helped along in the volume department with some Beauty Works hair extensions.
Here's how to copy her look in three simple steps:
1. First, scoop the top section of your hair (just above eye level) into a high ponytail and secure with a covered band. Backcomb it slightly to add volume, then twist your ponytail into a slightly messy bun and pin into place with Kirby grips.
2. Create soft waves in the rest of your hair by spritzing with heat protection spray, then tonging with a large-barreled tong. We love TRESemmé Perfectly (Un)done Curling Tong, £20, boots.com.
3. To finish, rake through the waves with your fingers, then hold your bun with one hand and use your fingers to slightly lift the hair around your hairline. This helps add volume up top. Finish with hairspray.
