The actress was promoting her film The Stag at a VIP screening in Leicester Square last night wearing an all Irish ensemble for the occasion.
Before jetting to Dublin this morning and Paris later today for Brian O'Driscoll's last game in the Ireland jersey, she was the star of the show at the UK premiere.
And the famous fashionista was clearly keen to promote Irish as she wore a magenta silk tee and 'Envelope pocket skirt' by Lennon Courtney, costing €160 and €159 respectively.
The brand is the brainchild of stylist duo Sonya Lennon and Brendan Courtney and is fast becoming the go-to label for Irish style stars.
She complemented the classy look with a pair of shoes from her own collection with Bourbon, from last season, topping it off with jewellery from Newbridge Silverware, which she is also a new spokesmodel for.
Meanwhile, back in Dublin, fans applauded as Joe Schmidt's squad boarded their flight to Paris yesterday evening – but there was no special welcome when they arrived in France, with each player carrying their own bag out of arrivals.
O'Driscoll will play his final game in the green of Ireland at the Stade de France tomorrow evening, with his parents Frank and Ger and wife Amy cheering him on from the stands.
It'll be a hectic weekend for Huberman but she was determined to attend the UK premiere, having missed the Irish opening last month.
"Having Amy here is amazing," 'Stag' producer Rebecca O'Flanagan told the Irish Independent.
"We really missed her at the Irish premiere so it makes things a bit more special. It feels like we're all on a school tour.
"This is the last big party before we head over to America."
Next month, the movie will be screened at the prestigious Tribeca Film Festival in New York.
