Stepping out at Grosvenor House hotel on June 22, Lohan and Tarabasov walked the red carpet for the Caudwell Children charity’s Butterfly Ball, which featured Grammy-winning headline act Burt Bacharach and singer Gabrielle.
Lohan also posted a behind-the-scenes photo of herself and her rumoured fiancé, thanking her hosts for the invitation and including a nod to Mean Girls with the hashtag #OnWednesdaysWeWearPink.
Loved up Lohan has been flaunting her romance as the pair holidayed in Cannes then Mauritius, the star putting her string of headline-making incidents firmly in the past.
“He’s a great guy,” Lohan told the UK Sun in March. “I’m really happy.”
Those who know her agree he has been a good influence. “She’s in a really good place,” a source close to Lohan told WHO. “She’s made a new life for herself.”
The couple has just returned to London, where Lohan now lives with Tarabasov, after jet-setting to Madrid.
They also recently spent time in Monaco and Cannes.
