1.Rachael Finch shares health news: ‘I have a cyst on my brain’.

After months of suffering relentless migraines, Rachael Finch sought help from her GP.

She saw eight different health professionals, tried many different tactics, and eventually one doctor ordered an MRI.

“I used to get really bad headaches and migraines every second or third day,” she told Practical Parenting. “It was horrible and I would wake up and just after recovering for a day… boom, I would suffer from another one.”

The MRI revealed the mum-of-two has an arachnoid cyst on the lower part of her brain.

While the cyst is not cancerous or dangerous, she does have to monitor it.

Oddly enough, the cyst was not actually causing the migraines, but they seem to have lessened now.

“The headaches went away and they don’t know where they came from,” she told the website. “I get headaches now once a month around that time of the month but it’s been very bizarre.”

2. Heath Ledger’s father has some thoughts on Michelle Williams’ surprise secret wedding.

"[She is] very private and I don't really like to make too many comments about her, but we are very happy," he added.

Heath, who tragically died in 2008, shares a daughter with Michelle, 12-year-old Matilda. They were together for three years after meeting on the set of Brokeback Mountain in 2004.

5. Chrissy Teigen says what we’re all thinking about Meghan Markle’s father.

It was intriguing at first. A reclusive former Hollywood lighting director thrust into the spotlight by his famous daughter’s engagement to a British royal.

But as the wedding approached, as Thomas Markle gave interview after interview, feeding the tabloid hunger for insight into his strained relationship with former Suits star, Meghan, the tide quickly turned.

What was once intriguing, started seeming, well, just plain exploitative.

Model Chrissy Teigen captured the mood perfectly over the weekend, tweeting images of one of the 74-year-old’s latest interviews.

“This guy…this guy sucks,” Teigen wrote. “What is wrong with him? Let your daughter be happy, please. This is embarrassing.” [sic]
