Christine Quinn seemingly takes brutal dig at estranged husband after he made bizarre request to her amid divorce

It looks as though Christine Quinn is having a 'brat summer', after she posted a cryptic Instagram picture referencing her ex-husband and Charli XCX's hit summer album.

The girlies are either 'demure' or 'brat' this summer - there is no in-between.

And it seems like Christine Quinn is very much going for the latter of the two, after her ex-husband, Christian Richard, filed for divorce earlier this year.

She may be taking a light hearted approach on the gram, but just five months ago, the businessman was arrested for assault with a deadly weapon, after an alleged domestic incident at the former couple's house.

Police claim that Christian had thrown a bag containing glass at Quinn but narrowly missed - instead striking their three-year-old son.

He was taken into custody the following day for returning to the family home, despite Christine having an emergency protective order in place.

Shortly after these incidents, Christian filed for divorce in April, after four years of marriage.

The pair's son, Christian Georges Dumontet, is named after his dad.

The Selling Sunset star posed on Instagram, sharing a video of her lounging on a boat.

And she shared some advice for others going though a breakup - seemingly a cryptic message directed at her ex.

In the clip, the 35-year-old was lying on the boat in a light pink bikini, and her long blonde hair blowing in the wind.

She captioned it: "Remember ladies, while you're healing he's balding."

Ouch!

She also referenced Charli XCX's hit album Brat, as she added the hashtags: "#brat #bratsummer #bratslay."

Following the divorce, Christian has requested a restraining order against the TV personality, in documents where he has denied all allegations of abuse against him.

The court documents state that: "He has never threatened violence and never engaged in any acts that could be construed as violence towards Ms. Quinn."

Court documents obtained by Page Six show that Christian had asked the court to remove the order that grants Quinn exclusive access to their home in California - because he received 'a utility bill in excess of $10,000'.

He has stated that not being able to have access to the property has led to 'thousands of dollars' in fines, which he cannot pay due to having no access to the letters.

Throughout the ongoing legal battle, Christine is also fighting to get full custody of their little boy, Christian.
