Britney Spears spoke out Wednesday for the first time since her 55-hour marriage to hometown pal Jason Allen Alexander, explaining what she did on her Las Vegas vacation during a phone call to MTV's ''TRL.'' ''I do believe in the sanctity of marriage; I totally do,'' said the singer, who had been dressed as a bride during her notorious MTV kiss with Madonna last summer. ''But I think I was in Vegas and it took over me.''
Spears, who had called host Damien Fahey from Los Angeles to promote her new video, ''Toxic,'' kept trying to bring the subject of the conversation back to her latest clip. Asked for further explanation of her quickly annulled Jan. 3 wedding, she said: ''I was in Vegas and I was with my friend, and we hit it off completely, and let's talk about something else.''
The 22-year-old singer said she was shocked by all the media attention given to her abortive nuptials. ''We landed on Mars that day,'' she noted. ''Why aren't they talking about that?'' Asked whether she had feelings for Alexander, she said: ''That's a personal question, but I do have a video coming out, and it's really cool.''
