With their busy schedules, it's not that often that they get to see each other.
But there was a chance for Zara Phillips to catch up with some of her closest girlfriends this week.

Princess Anne's daughter looked delighted to see The Saturdays singer Una Healy, Corrie star Katherine Kelly, and Alpine ski racer Chemmy Alcott at at the Rugby For Heroes Gala dinner at Twickenham Stadium.
The girls, who were all guests at Zara's wedding, shared hugs – and a few laughs too – as they posed for pictures on the pitch.
No doubt the group had fun reminiscing about the royal nuptials, and engaged Una was sure to have picked up some wedding planning tips from the Queen's grandaughter.
The 30-year-old pop star looked slim and gorgeous in a strapless butterfly print dress.
She has clearly had no problems regaining her figure after welcoming baby Aiofe Belle eight weeks ago.
It wasn't just a girls night out though. Zara and Una brought along their other halves, rugby stars Mike Tindall and Ben Foden.
Both the boys looked dapper in tuxedos and bow ties.
