Spoiler alert! Lisa Vanderpump's adopted son begins his search for his biological parents — and the process is harder than expected for The Real Housewives of Beverly Hills star.
"Hold on a second. Oh God, I'm not doing this right," Lisa, 56, tells her son Max Todd before bursting into tears on tonight's episode, which airs at 9 p.m.

The Bravo-lebrity then proceeds to walk out of the room, overwhelmed by her emotions as she sits next to her adult son, who is rarely seen on the reality series.
Lisa, who is also mom to biological daughter Pandora, has opened up about her son's adoption on her blog in the past, revealing that she has always been open with him about his past.
"Are the children different to me? Do I love them differently? Is their a biological connection that makes a relationship stronger? I honestly don't have the answer to that," she wrote. "Each child is different, each relationship varies, but one thing I know for sure is biology has little to do with emotional connections, of that Max and I are sure."
She continued, "I encourage them to be independent of me, but they know I am there to catch them if they fall, then to put them back on that slippery slope we know as life."

When asked how she would feel if he wanted to meet his birth parents, she replied, "Of course I would care, but I've had the good parts. Nobody can take him from me now, right?"
