The sister of Foreign Secretary Boris Johnson was the first to leave in a double eviction, joining Maggie Oliver as the latest housemate to be eliminated from Celebrity Big Brother. 

In scenes which aired before her interview with Emma Willis, the famed journalist addressed the secret behind her sibling’s iconic ‘do. 

After a swipe from rival Ann Widdecombe - who mistakingly thought she’d been voted out of Celebrity Big Brother - Rachel jumped to Boris’ defence. 

"What is there to laugh at? I honestly don't know what you're talking about,” Rachel barked as Boris’ signature mop came under question. 

Ann teased: “Come on Rach, you may adore him but even you've got to laugh at his hair.”

"We have uncontrollable hair!” Rachel snapped. “His hair doesn't lie flat, it never has.

"[Brother] Jo has got thick hair that sticks up. [Brother] Leo has thick hair that sticks up. 

“It doesn't lie flat, our hair. I actually have to flatten mine."

Rachel became the second housemate to be evicted from Celebrity Big Brother last night, following India Willoughby’s axe last week. 

During her exit, she took a surprise swipe at RuPaul contestant Shane Janek, after a clash over parmesan cheese. 

Viewers were gutted to see Rachel leave, with one posting: “Rachel came across really well and whilst I think her time was tonight... she was a great housemate!”

Another added: “Proper guttered about Rachel being evicted. I thought she was a good character.”

A third complimented: "You went too soon Rachel. Really enjoyed you as a housemate on a fantastic series of #cbb. I felt your pain over the Parmesan!”

What’s more Rachel dropped a shock bombshell about fellow housemate Andrew Brady, which left Emma completely speechless. 

Maggie soon followed Rachel just minutes later and revealed that Ann would be the only housemate that she won’t be speaking to once the current cycle of Celebrity Big Brother has come to a close. 

Celebrity Big Brother continues tonight at 10.35pm on Channel 5.
