Lindsay Hubbard cast doubt on Amanda Batula and West Wilson’s romance timeline — and called Batula’s estranged husband, Kyle Cooke, a “decoy” — during “Watch What Happens Live” Tuesday night.

Her fellow guest — and “Summer House” co-star — Bailey Taylor told viewers Batula, 34, and Cooke, 43, were “heavily kiss[ing]” in front of their friends in February, despite being separated .

When Taylor, 29, asked Wilson, 31, why the exes were making out at the time, he allegedly replied, “Let them do their thing.”
