Jessica Simpson, 30, and her boyfriend Eric Johnson, 31, were engaged on Thursday, just days after it was announced her ex, Nick Lachey, and his long-time love Vanessa Minnillo were set to tie the knot, according to an UsMagazine report.

As Simpson shopped at the Oak Park Mall in Kansas City yesterday, she was sporting a huge ring on her wedding ring finger, according to the report.

The two started dating in May while Johnson, a former NFL player, was estranged from his first wife Keri. Their divorce was finalized last month.
