Sunrise stars have been subjected to plenty of pranks on the breakfast show over the years.
In a hilarious video posted to Instagram, Natalie looked terrified as she arrived to the office and a creepy clown jumped out in front of her.
‘F**k. I hate you. I had a heart attack,’ she yelled.
Mark was also left shocked and speechless as the clown jumped out in front of him as he arrived to work.
The sports presenter yelled in fear as he was greeted by the masked staffer at the door’s entrance.
Mark recently confirmed his split with his wife Rachel after 22 years of marriage earlier this month.
The Sunrise star and his former partner, who married in 2001, confirmed they quietly parted ways in recent months in a statement.
‘At the start of the year, after a great deal of reflection and 22 years of marriage, Rach and I came to the conclusion that a separation was best for us,’ Beretta told Daily Mail Australia through a Seven spokesperson.
‘We remain good friends, and our two children and grandchild remain our focus and priority as we move forward with love, dignity, and respect.’
According to a new report, the presenter has been leaning on his Sunrise family for support during this difficult time.
‘They are a tight-knit group over there at Sunrise, always have been. David Koch has always had a hand on Beretts’ back. He has been a tower of strength,’ an insider told this week’s New Idea magazine.
‘Everyone has been incredibly supportive. They are really sad about the split as they all love Rach.
Mark and his ex remain close friends and are committed to being there for children Ava and Daniel and grandson Arlo.
