Anyone willing to wade into the chaos of Lindsay Lohan's life is either very brave or very foolish. Or maybe both. The New York Daily News says the slowly-but-surely spiraling starlet, 23, is getting "more serious" with a Gucci model-cum-former "The City" co-star named Adam Senn, whom she has repeatedly said is just a friend. And here's a giant red flag: Her mom is a fan. "Dina really likes him," an insider tattles to the paper. "She thinks he is 'good for her.'" Word is, LiLo brought Senn, 25, along to a dinner celebrating sister Ali's sweet 16 last week so he could meet the clan. Fortunately, he was spared any major fireworks thanks to the absence of her bottom-feeding father, Michael, who is currently disputing reports that he's $40,000 behind in child support payments (it appears he may owe only $15,000, which, by our math, still adds up to deadbeat dad-dom). "Everything that's gone on between Lindsay and her dad has really taken a toll on her," maintains the source. "Adam is the one really positive thing going on in her life." Uh, no pressure or anything, dude. The mole says the two were texting and calling each other over the holiday. "Adam is a good guy," concludes the source, "and Lindsay is definitely starting to turn to him when things get bad." As for the onetime actress's ex, Samantha Ronson, she's hanging with former peacemaker John Mayer and quoting loaded Jay-Z lyrics.
