According to TMZ Sports, McGregor purchased a Lamborghini 63 Yacht By Tecnomar, which has a starting price of $3.9 million but could cost even more depending on customization.
TMZ Sports tweeted an artist rendering of the boat, which is expected to be completed by next summer:
Excited to see the finished result during next season's yachting season."
McGregor said last month, however, that he plans to return to combat sports by boxing Manny Pacquiao.
McGregor's manager, Audie Attar, added that the plan is for McGregor to return to UFC in 2021 after fighting Pacquiao.
