She's only three months old but little Sadie O'Driscoll could be kick-starting a 'Baby Gaga' trend.
The tiny tot was photographed wearing an oversized set of noise cancelling headphones when her dad took to the pitch on Saturday.
The daughter of Brian O'Driscoll and actress Amy Huberman wore the bubble gum pink headphones to protect her ears from the roaring Lions' fans.
Mum Amy made sure she is one trendy tot; co-ordinating her headphones with a pale pink wool hat and puffa jacket.
And adoring mum Amy looked supportive and chic in a royal red sports hoodie and jeans as she cheered Brian on. The author told her Twitter fans she was feeling on edge before the match and suffering from "nervous rugby burps".
Match anxiety aside, 34-year-old actress Amy has been enjoying a girly holiday Down Under with her daughter and cousin Noleen.
They have visited animal sanctuaries, taken a road trip and visited the Neighbours set.
But Amy admits travelling with a tiny tot can be a challenge.
"So that journey was pretty much like a dirty protest in a Cambodian jail 35k in the air," she wrote once she touched down in Oz. "But we're here. With s*** in our hair. G'day."
Meanwhile, Brian has been working hard on and off the pitch as part of the Lions Tour.
The squad's gearing up for the Sydney showdown this Saturday.
