Is Brian Austin Green back with his ex-fling Tina Louise? The 47-year-old "Beverly Hills, 90210" star was spotted looking pretty comfortable with the hot tattooed model while at the beach in Malibu, CA earlier this week. Despite taking care of their three children while his estranged wife Megan Fox was in Puerto Rico with her new man Machine Gun Kelly, Brian Austin Green was NOT seen sporting a dad bod on his PDA-filled date on Monday, August 31. Instead, he was baring a six-pack on his barely-clothed afternoon outing with Tina Louise. Their date comes just days after he said "never say never" when asked about rekindling his marriage with the "Transformers" actress.
