(NEW YORK) -- Lindsay Lohan will make her live theater debut in London next month, but in the meantime, she's reportedly fallen for an older investment banker named Patrick Mahony.
An insider tells In Touch magazine the 28-year-old Mean Girls star and Mahony are living together under the same roof, along with Patrick’s two young daughters.
A second source tells the magazine, “Lindsay helps the kids take baths,” adding, “She really pitches in looking after them, and the girls really like her.”
The source goes on to say Lohan is doing better than ever, noting, “She’s finally in a mature relationship with a really grounded guy.”
Lohan will star in a London production of David Mamet's Speed-the-Plow, opening Sept. 24.
