Blackstone Group LP (BX) is looking into a possible deal to buy Anheuser-Busch InBev NV's (BUD) theme parks, a person familiar with the matter said Wednesday.

InBev, which bought Anheuser-Busch last year, has been looking for months to find a buyer for theme parks operated under Busch Entertainment Corp. The amusement parks include SeaWorld and Busch Gardens.

Any deal would allow InBev to pay down debt incurred from its acquisition of Anheuser-Busch. For Blackstone, it would expand the private-equity company's theme-park holdings. It already owns 50% of Universal Orlando; the other 50% is owned by NBC Universal, which is 80% owned by General Electric Co. (GE) and 20% by Vivendi SA (VIVDY).

No deal was expected imminently.

Anheuser-Busch InBev couldn't immediately be reached for comment.
