PARIS — France’s first lady said in an interview published Wednesday that she regrets posting on Twitter a comment that many French read as a not-so-veiled dig against the mother of President Francois Hollande’s four children.

About four months after causing the stir dubbed ‘‘Tweetgate,” Valerie Trierweiler told regional newspaper Ouest-France that her comment on Twitter was a ‘‘mistake’’ and she’s learned from it.

During France’s legislative elections in June, Trierweiler sent tongues wagging by tweeting words of encouragement to a dissident Socialist running against Segolene Royal — Hollande’s former partner. Royal was vying to represent a region in western France, and ended up losing.

Trierweiler, a journalist who once had her own cable TV show, admitted she had been clumsy, and had not yet realized that after Hollande took office in May she was ‘‘no more just a simple citizen.’’

‘‘It won’t happen again,’’ she was quoted as saying of the tweet.

Trierweiler took the comment off her Twitter account weeks ago, but the fallout lives on: A leading satirical TV show continues to parody the alleged rivalry between Trierweiler and Royal, with Hollande depicted as uncomfortable — and essentially powerless to stop it — in the middle.

A new poll released Wednesday suggests that most French do not have a positive opinion of Trierweiler. Hollande’s popularity, meanwhile, has been sliding in recent months — although that is probably because of a variety of factors including a sluggish French economy and high unemployment.

Asked whether her fellow journalists had been unfair over the tweet, Trierweiler told Ouest-France: ‘‘The handling [of it] especially seemed out of proportion to me.’’

She added ‘‘being at the side of the president requires me . . . to have concerns that are less personal.’’
