The glamourous TV presenter was snapped arriving for the filming of Celebrity Juice, the panel show she is a regular on, looking glowing in a stylish work outfit.
Earlier Holly tweeted to say she was feeling nervous about returning to work and leaving Belle, and older son, Harry at home:
'First day back at work today!!!! Cant wait to start the new series of Celeb juice, feeling slightly nervous! Wander if I can still do it!
'The weirdest thing is going to be getting ready, forgotten what my face looks like with tv slap on! Proper clothes,not just my scruffs!!! X'
Holly is expected to return to our screens next week when she heads back to her This Morning presenting job, which has been covered by mum-to-be jenni falconer while Holly was on maternity leave.
Her TV return comes five months after giving birth to baby Belle.
