Taylor Swift and Hugh Jackman could both be subpoenaed in the enduring legal battle between their close pal Blake Lively and her “It Ends With Us” director Justin Baldoni, who she has accused of sexual harassment and a retaliatory smear campaign.

Swift, 35, was referenced in Baldoni’s $400 million defamation suit against the “Gossip Girl” alum, her husband Ryan Reynolds and her publicist Leslie Sloane.

Jackman, 56, costarred with 48-year-old Reynolds in “Deadpool & Wolverine,” which dominated a swath of the box office last summer alongside “It Ends With Us.”

“Anyone that had any knowledge of this situation will be subpoenaed, no matter of their celebrity status,” one insider told People Thursday.

A separate source dismissed the threat of subpoenas as “smoke and mirrors and trying to distract from the allegations against Baldoni.” They said the “cardigan” singer — who is godmother to Lively and Reynolds’ four children — and “Music Man” star are “not privy to anything going on.”

Lively, 37, filed a complaint in late December accusing Baldoni, 41, of having sexually harassed her on the set of the domestic violence drama, and unleashing an online smear campaign to discredit her.

She formally sued Baldoni on New Year’s Eve, the same day he filed a $250 million libel lawsuit against The New York Times’s coverage of Lively’s claims.

The following month, Baldoni, who denies the allegations against him, filed a defamation suit against Lively, Reynolds and Sloane, also accusing them of civil extortion.

Text messages included in Baldoni’s lawsuit appear to show Lively referring to Swift and Reynolds as her “dragons.” Swift has remained mum on anything concerning the case.

The trial is currently scheduled to start next March.

The Daily News has reached out to representatives for Swift and Jackman. Lively and Baldoni’s attorneys did not immediately respond to The News’ request for comment.
