She was discovered by Playboy while working as a page for the Queen for a Day TV game show. She went on to work at the Playboy Club as a Bunny and later as a Bunny Mother.
Jo, who is of Norwegian and Spanish descent, was married to baseball player Bo Belinsky for five years (1970 to 1975).[1]
She was nicknamed "G.I. Jo" for her United Service Organizations tours to entertain the troops during the Vietnam War. She first went to Vietnam to meet 2LT Jack Price of Company B, 2nd Battalion, 503rd Infantry, 173rd Airborne Brigade. Price sent to Hugh Hefner in November 1965 a letter purchasing a lifetime subscription to Playboy, for which the magazine promised that a Playmate would deliver the first issue personally. The letter requested Collins as the Playmate. Price was wounded in action on 3 January 1966, forcing Collins to reschedule the visit to before he was medically evacuated on 13 January. General Ellis W. Williamson named her an honorary Sky Soldier, and Company B renamed itself "Playboy Company".[2][3]
In December 1979, Jo posed for the "Playmates Forever!" pictorial. In 1998, Jo reunited with Jack Price for an online interview with Playboy fans.
