Wahlberg was in NYC when he was asked about working out with his "Instant Family" co-star. He doesn't even joke, telling us Spencer is an "inspiration."
He says the actress is "killing it" right now, and joining him on his early morning grind sessions as he tries to stay as he works on functional movement.
Spencer has also signed on to taking the "Transformer" star's supplements, Performance Inspired Nutrition. Looks like Spencer is about to start booking some action roles.
