Terri SPYING ON ROBERT & RORIE!

AS YOUNG LOVE BLOOMS, TABS ARE BEING KEPT

Terri Irwin has joined Instagram, but the move has got everyone wondering, why now?

The mum of two has been a regular on Twitter for years, but always left Instagram to her children, Bindi and Robert.

Yet she's taken the plunge, creating an account under the handle 'terriirwincrikey'. And our source believes she's done so in order to keep a close eye on Robert's girlfriend, Rorie Buckey.

Indeed, just days before Terri, 59, signed up to the social media platform, Rorie, 19, made her own account public. It had previously been private.
