Earlier this week, Billie rocked a pretty plaited updo and now Sam's mixed up her mid-length locks with a hairpiece.
The star worked the look on a girly night out at Sugar Hut last night (13 June).
Both girls' styles come courtesy of Brentwood hair salon, Mars and Venus. While Billie's style requires a little more fiddly fingerwork, Sam's pony can be achieved in one minute flat. Yes, really.
She rocked Angela Sleek Ponytail Hairpiece in Light Chocolate from Annabelle's Wigs.
At £49, it's a pricey way of doing a pony but perfect if you're not blessed with super-shiny, long tresses. That'll be us then!
Simply put your natural hair in a ponytail - Sam's gone for a classy middle of the head point rather than ultra-high or nape of the neck. Then attach the hairpiece over the top using the clip provided, wrap it round your pony and use your hands to blend it in.
Annabelle's Wigs are a favourite with the likes of The Saturdays, Pixie Lott and Kelly Osbourne but for a purse-friendly alternative, try Love Hair Extensions Silky Sue Ponytail, £24.95.
Done, done and done.
