'Congratulations to my beautiful sister in law @ninaginz and my brother @mikelohan!!!' she wrote.

Lindsay tagged her 22-year-old fiance Egor's @e2505t handle and added hashtags '#family ties, #LoveYou' and '#trendsoflifelove.'

In the photo, Michael beams as Nina raises her hand over her mouth and flashes her diamond ring as they cuddle up in front of a beach hut.

Lindsay is the oldest of four children from her mother Dina Lohan's marriage to ex-husband Michael Lohan, including Michael Jr and her sister Ali, 22, and brother Cody, 19, who are both models.

Her father also has three other children, who are Lindsay's half-siblings: a 'love child' Ashley Kaufmann, 20, as well as two sons -  Landon, three, and one-year-old Logan - from his marriage to Kate Major.

Lindsay has been living in London for the past few years after fleeing the LA lifestyle, where she was often in the spotlight for her many arrests and stints in rehab.

She recently moved in with Egor in London and has been working to rebuild her acting career and health.

But the Parent Trap star has been spending time back in her native New York visiting family since her engagement.

She was seen shopping with sister Ali, as well as singing onstage at a Duran Duran concert she attended with parents Dina and Michael Lohan last week.

The actress also revealed that she has been studying Islam to satisfy her intellectual curiosity, and is open to converting.

'I'm a very spiritual person and I'm really open to learning,' the former child star told The Sun.

'America has portrayed holding a Koran in such a different way to what it actually is.'

But she confessed she has yet to read the entire Koran, saying: 'Do you know how long that would take?'
