Lindsay Lohan

The 27-year-old actress, who completed 90-days of court-ordered treatment in rehab at the end of July, recently began seeing the ex-Philadelphia Eagles player, whom she has known for seven years, and he has already formed a bond with her whole family.

A source told "She is very happy and very committed to staying sober. He drinks but not irresponsibly and not in front of her. He is close to her whole family."

The 30-year-old Texas-native, who starred on the 2011 Bravo reality TV series 'Most Eligible Dallas,' also recently told the New York Post's Page Six that he is trying to support Lindsay.

He said:"We've hung out. But I have been a friend trying to support her for many years now."

He added: "She's completely sober now. She's in a great place and working hard and meeting with all the right people."

'The Canyons' star's last serious relationship was with DJ Samantha Ronson, which ended in 2009 after a tumultuous year.

Samantha's mother Ann Dexter-Jones later admitted she "interfered" with the couple and told her 35-year-old daughter she couldn't support their relationship as she became "anxious about Samantha's safety and wellbeing" because of Lindsay's alleged "classic psychotic behaviour".
