Alex, who shares two sons – Teddy, three, and Kit, one – with her husband Charlie Thomson, recently returned to work following a relaxing family getaway.
Sharing pictures from her break online, she revealed it was possibly their “best holiday yet”.
The Welsh-born TV star told fans she was “grateful” for the two week trip which saw her regularly visit the beach with her young children.
A snap captioned “reunited at last” seemed to show Alex’s son with his grandparents.
